    Robust Programmable 2D Position Sensor Family with Arbitrary Output Function  
    Release Note: Revision bars indicate significant changes to the previous document.  
    1. Introduction  
    The HAL 37xy family comprises the second generation of sensors using the proprietary  
    Micronas 3D HALtechnology. This new family has several members. HAL 372x  
    provides a linear, ratiometric analog output signal with integrated wire-break detection  
    working with pull-up or pull-down resistors. Compared to HAL 372x, the HAL 371x is  
    splitting the 360° measurement range either into four repetitive 90° (MOD 90°) or three  
    120° (MOD 120°) segments. HAL 373x features digital output formats like PWM and  
    SENT (according to SAE-J2716 release 2010). The digital output format is customer  
    programmable. The PWM output is configurable with frequencies between 0.2 kHz and  
    2 kHz with up to 12 bit resolution.  
    Conventional planar Hall technology is only sensitive to the magnetic field orthogonal to  
    the chip surface. In addition to the orthogonal magnetic field, HAL 37xy is also sensitive  
    for magnetic fields applied in parallel to the chip surface. This is possible by integrating  
    vertical Hall plates into the standard CMOS process.  
    The sensor cell can measure three magnetic-field components BX, BY, and BZ. This  
    enables a new set of applications for position detection, like wide distance, angle or  
    through-shaft angular measurements. The Table 1–1 below describes the different family  
    members.

    DATA SHEET  
    HAL 371x, HAL 372x, HAL 373x  
    On-chip signal processing calculates the angle from two of the magnetic field components  
    and converts this value to an output signal. Due to the measurement method, the sensor  
    exhibits excellent drift performance over the specified temperature range resulting in a  
    new class of accuracy for angular or linear measurements.  
    Additionally to the built-in signal processing, the sensor features an arbitrary programm-  
    able linear characteristic for linearization of the output signal (with up to 33 setpoints).  
    Major characteristics like gain and temperature dependent offset of X/Y- and Z-channel,  
    reference position, phase shift between X/Y- and Z-signal, hysteresis, low-pass filter  
    frequency, output slope, and offset and clamping levels can be adjusted to the magnetic  
    circuitry by programming the non-volatile memory.  
    The sensors contain advanced on-board diagnostic features that enhance fail-safe detec-  
    tion. In addition to standard checks, such as overvoltage and undervoltage detection and  
    wire break, internal blocks such as ROM and signal path are monitored during normal  
    operation. For devices with a selected PWM output, the error modes are indicated by a  
    changing PWM frequency and duty-cycle. For SENT output a dedicated error code will be  
    transmitted.  
    The devices are designed for automotive and industrial applications and operate in a  
    junction temperature range from 40 °C up to 170 °C.  
    The sensors are available in a four-pin leaded transistor package TO92UP, as well as in  
    a SOIC8 package.  
    1.1. Major Applications  
    Due to the sensor’s versatile programming characteristics and its high accuracy, the  
    HAL 37xy is the optimal system solution for applications such as:  
    – Linear movement measurement,  
    • EGR valve position  
    • Clutch pedal position  
    • Cylinder and valve position sensing  
    – Rotary position measurement, like  
    • Gear selector

    3. Functional Description  
    3.1. General Function  
    HAL 371x, HAL 372x and HAL 373x are 2D position sensors based on the Micronas  
    3D HALtechnology. The sensors include two vertical and one horizontal Hall plate with  
    spinning current offset compensation for the detection of X, Y or Z magnetic field compo-  
    nents, a signal processor for calculation and signal conditioning of two magnetic field  
    components, protection devices, and a ratiometric linear analog, PWM or SENT output.  
    The spinning current offset compensation minimizes the errors due to supply voltage  
    and temperature variations as well as external package stress.  
    The signal path of HAL 37xy consists of two channels (CH1 and CH2). Depending on  
    the product variant two out of the three magnetic field components are connected to  
    Channel 1 and Channel 2.  
    The sensors can be used for angle measurements in a range between 0° and 360° (end  
    of shaft and through shaft setup) as well as for robust position detection (linear move-  
    ment or position). The in-system calibration can be utilized by the system designer to  
    optimize performance for a specific system. The calibration information is stored in an  
    on-chip EEPROM.  
    The HAL 37xy is programmable by modulation of the output voltage. No additional  
    programming pin is needed.

    The sensor signal path contains two kinds of registers. Registers that are readout only  
    (RAM) and programmable registers EEPROM/NVRAM. The RAM registers contain  
    measurement data at certain steps of the signal path and the EEPROM/NVRAM registers  
    have influence on the sensors signal processing.

    3.2.2.1. RAM Registers  
    TADJ  
    The TADJ register contains the digital value of the sensor junction temperature. It has a  
    length of 16 bit and is binary coded. From the 16 bit only the range between 0 32767  
    is used for the temperature information. Typically the temperature sensor is calibrated  
    in the way that at 40 °C the register value is 100 LSB and at 160 °C it is 12000 LSB.  
    CH1_COMP and CH2_COMP  
    CH1_COMP and CH2_COMP register contain the temperature compensated magnetic  
    field information of channel 1 and channel 2. Both registers have a length of 16 bit each  
    and are two’s-complement coded. Therefore, the register values can vary between  
    32768 32767.  
    ANGLE_IN_CH1 and ANGLE_IN_CH2  
    ANGLE_IN_CH1 and ANGLE_IN_CH2 register contain the customer compensated  
    magnetic field information of channel 1 and channel 2 used for the angle calculation.  
    These registers include already customer phase-shift, gain and offset correction as well  
    as an hysteresis. Both registers have a length of 16 bit each and are two’s-complement  
    coded. Therefore, the register values can vary between 32768 32767.  
    ANGLE_OUT  
    The ANGLE_OUT register contains the digital value of the position calculated by the  
    angle calculation algorithm. It has a length of 16 bit and is binary. From the 16 bit only  
    the range between 0 32767 is used for the position information. Position can either  
    be an angular position (angle) or a virtual angle calculated out of two magnetic field  
    directions in case of linear position measurements.  
    DAC  
    The DAC register contains the digital equivalent of the output voltage, PWM output  
    duty-cycle or the SENT data. It has a length of 16 bit and is binary. From the 16 bit only  
    the range between 0 32767 is used for the position information. Position can either  
    be an angular position (angle) or a virtual angle calculated out of two magnetic field  
    directions in case of linear position measurements.  
    ANGLE_AMP  
    The ANGLE_AMP register contains the digital value of the magnetic field amplitude  
    calculated by the angle calculation algorithm. From mathematical point of view the ampli-  
    tude can be calculated from the signals in channel 1 and channel 2 (X/Y/Z-components).

    Example:  
    Amplitude = CH12 + CH22  
    The angle calculation algorithm adds a factor of roughly 1.6 to the equation for the  
    magnetic amplitude. So the equation for the amplitude is defined as follows:  
    ANGLE_AMP 1,6 CH12 + CH22  
    DIAGNOSIS  
    The DIAGNOSIS register identifies certain failures detected by the sensor. HAL 37xy  
    performs self-tests during power-up of the sensor and also during normal operation.  
    The result of these self tests is stored in the DIAGNOSIS register. DIAGNOSIS register  
    is a 16 bit register.

    PROG_DIAGNOSIS  
    The PROG_DIAGNOSIS register allows the customer to identify errors occurring during  
    programming and writing of the EEPROM or NVRAM. The customer must check the first  
    and second acknowledge. It is mandatory to activate the Diagnosis Latch bit during end  
    of line testing. Additionally, CLAMP-LOW must be set to 100% in case of HAL 3711 and  
    HAL 373x. Otherwise programming errors will not be indicated by the second acknowl-  
    edge. To enable debugging of the production line it is recommended to read back the  
    PROG_DIAGNOSIS register and the DIAGNOSIS register in case of a missing second  
    acknowledge. Please check the “HAL 37xy, HAR 37xy User Manual” for further details.  
    The PROG_DIAGNOSIS register is a 16 bit register. The following table shows the

    Micronas IDs  
    The MIC_ID1 and MIC_ID2 registers are both 16 bit organized. They are read-only and  
    contain TDK-Micronas production information, like X/Y position on the wafer, wafer  
    number, etc.

    Customer IDs  
    The CUST_ID1 and CUST_ID2 registers are both 16 bit organized. These two registers  
    can be used to store customer production information, like serial number, project  
    information, etc.  
    CH1/CH2_GAIN  
    CH1/CH2_GAIN can be used to compensate a phase-shift between channel 1 and  
    channel 2. The register has a length of 16 bit. It is possible to make a phase shift correction  
    of 75°. The step size and therefore the smallest possible correction is 0.002°. The register  
    is two’s-complement coded and ranges from 32768 to 32767. The register value is sin  
    function based.  
    Neutral value for this register is zero (no Phase-shift correction).  
    Note  
    In case the phase-shift correction is used, then it is necessary to adapt the  
    settings of GAIN_CH2 too. For details see definition of GAIN_CH2.  
    GAIN_CH1 and GAIN_CH2  
    GAIN_CH1 and GAIN_CH2 can be used to compensate amplitude mismatches between  
    channel 1 and channel 2. TDK-Micronas delivers pre calibrated sensors with compensated  
    gain mismatch between channel 1 and channel 2. Nevertheless it is possible that due to  
    the magnetic circuit a mismatch between channel 1 and channel 2 gain occurs. This can  
    be compensated with GAIN_CH1 and GAIN_CH2.  
    Both registers have a length of 16 bit and are two’s-complement coded. Therefore, they  
    can have values between 32768 and 32767 (2 2). For neutral settings both register  
    values have to be set to 1 (register value 16384).  
    In case that the phase-shift correction is used it is necessary to change also the gain of  
    channel 2 (see also CH1/CH2_GAIN). If phase-shift correction is used the corresponding  
    register has to be set to  
    16384

    GAIN_CH2 =  
    Note  
    In case GAIN_CH1 or GAIN_CH2 exceed the range of 2 2 (32768   
    32767), then it is possible to reduce the gain of the opposite channel for  
    compensation.

    CUST_OFFSET  
    CUST_OFFSET can be used to compensate an offset in channel 1 and channel 2.  
    TDK-Micronas delivers pre calibrated sensors. Nevertheless it is possible that due to  
    the magnetic circuit an offset in channel 1 and channel 2 occurs. This can be compen-  
    sated with CUST_OFFSET.  
    The customer offset can also have a temperature coefficient to follow the temperature  
    coefficient of a magnet. The customer offset consists of a polynomial of second-order  
    represented by the three registers CUST_OFFSET1...3.  
    The customer offset can be added to channel 1 and/or channel 2 by the selection  
    coefficients CUST_OFFSETCH1 and CUST_OFFSETCH2. Additionally these two  
    registers can be used to scale the temperature dependent offset between 0% and 100%.  
    All five registers have a length of 16 bit each and are two’s-complement coded. There-  
    fore, they can have values between 32768 and 32767.  
    HYSTERESIS  
    HYSTERESIS defines the number of digital codes used as an hysteresis on channel 1  
    and channel 2 before the angle calculation. The purpose of this register is to avoid  
    angle variation on the ANGLE_OUT register and finally on the output signal due to the  
    noise on the ANGLE_IN_CH1 and ANGLE_IN_CH2 signals.  
    The register has a length of 16 bit and is two’s complement number.  
    It is possible to program a hysteresis between 1 LSB and 16383 LSB. The register  
    value itself must be stored as a negative value.  
    The hysteresis function is deactivated by setting the register value to zero.

    OUT_ZERO  
    OUT_Zero defines the reference position for the angle output. It can be set to any value  
    of the output range. It is the starting point/reference for the 33 setpoints. OUT_ZERO  
    has a register length of 16 bit and it is two’s-complement coded.  
    Note  
    Before reading ANGLE_OUT it is necessary to set OUT_ZERO to 0.

    Secondly this angle can be used to shift the PI discontinuity point of the angle calculation to  
    the maximum distance from the required angular range in order to avoid the 360°-wrapping  
    of the output due to noise.  
    PRE_OFFSET  
    The PRE_OFFSET register allows to shift the angular range to avoid an overflow of the  
    internal 16 bit calculation/signal path.  
    The PRE_OFFSET register has a length of 16 bit and is two’s-complement coded.  
    OUT_GAIN  
    OUT_GAIN defines the gain of the output signal. The register has a length of 16 bit and is  
    two’s-complement coded. OUT_GAIN = 1 is neutral setting and leads to a change of the  
    output signal from 0% to 100% for an angle change from 0° to 360° (if OUT_OFFSET is  
    set to 0).  
    OUT_GAIN can be changed between 64 and 64.

    OUT_OFFSET  
    OUT_OFFSET defines the offset of the output signal. The register has a length of 16 bit  
    and is two’s complement coded. OUT_OFFSET = 0 is neutral setting and leads to a  
    change of the output signal from 0% to 200% of full scale for an angle change from 0° to  
    360° (If OUT_GAIN is set to 1).  
    OUT_OFFSET can be changed between 200% and 200% of full scale.  
    OUT_OFFSET = 0 leads to a voltage offset of 0% of full scale and OUT_OFFSET = 32768  
    leads to a offset of 200% of VSUP  
    .
    Clamping Levels (CLAMP-LOW & CLAMP-HIGH)  
    The clamping levels CLAMP_LOW and CLAMP_HIGH define the maximum and mini-  
    mum output voltage of the analog output. The clamping levels can be used to define the  
    diagnosis band for the sensor output. Both registers have a bit length of 16 bit and are  
    two’s-complemented coded. Both clamping levels can have values between 0% and  
    100% of full scale.  
    Magnetic Range Check  
    The magnetic range check uses the magnitude output and compares it with an upper and  
    lower limit threshold defined by the registers MAG-LOW and MAG-HIGH. If either low or  
    high limit is exceeded then the sensor will indicate it with an overflow on the sensors out-  
    put (output high clamping).  
    MAG-LOW  
    MAG-LOW defines the low level for the magnetic field range check function. This register  
    has a length of 16 bit and is two’s complement number.  
    MAG-HIGH  
    MAG-HIGH defines the high level for the magnetic field range check function. This register  
    has a length of 16 bit and is two’s complement number.

    3.3. Output Linearization  
    In certain applications (e.g. through shaft applications or position measurements) it is  
    required to linearize the output characteristic. The resulting output characteristic “value  
    vs. angle/position” is not a linear curve as in the ideal case. But it can be linearized by  
    applying an inverse nonlinear compensation curve.

    The constraint of the linearization is that the input characteristic has to be a monotonic  
    function. In addition, it is recommended that the input does not have a saddle point or  
    inflection point, i.e. regions where the input is nearly constant. This would require a high  
    density of set points.  
    To do a linearization the following steps are necessary:  
    – Measure output characteristics over full range  
    – Find the inverse (Point-wise mirroring the graph on the bisectrix)  
    – Do a spline fit on the inverse  
    – Insert digital value of set point position into spline fit function for each set point (0, 1024,  
    2048, , 32768)  
    – Resulting values can be directly entered into the EEPROM

    Customer Lock  
    The Output Short Detection feature is implemented to detect a short circuit between two  
    sensor outputs. The customer can define how the sensor should signalize a detected short  
    circuit (see table above). The time interval in which the sensor is checking for an output  
    short and the detectable short circuit current are defined in Section 4.8. on page 33.  
    This feature should only be used in case that two sensors are used in one module. In  
    case that the Output Short Detection is not active both sensors will try to drive their out-  
    put voltage and the resulting voltage will be within the valid signal band.  
    Note  
    The Output Short Detection feature is only active after setting the Customer  
    Lock bit and a power-on reset.

    3.5. On-board Diagnostic Features  
    The HAL 37xy features two groups of diagnostic functions. The first group contains basic  
    functions that are always active. The second group can be activated by the customer  
    and contains supervision and self-tests related to the signal path and sensor memory.  
    Diagnostic features that are always active:  
    – Wire break detection for supply and ground line  
    – Undervoltage detection  
    – Thermal supervision of output stage (overcurrent, short circuit, etc.)  
    – EEPROM self-test at power-on  
    Diagnostic features that can be activated by customer:  
    – Continuous EEPROM self-test  
    – ROM parity check  
    – Output signal clamping  
    – A/D converter clipping  
    – Continuous DSP self-test  
    – Magnetic range detection  
    – Overvoltage detection  
    In case of HAL 3715 and HAL 372x, the sensor indicates a fault immediately by switching  
    the output signal to the selected error band in case that the diagnostic mode is activated  
    by the customer. The customer can select if the output goes to the upper or lower error  
    band by setting bit number 7 in the CUST_SETUP register (Table on page 21). An output  
    short drives the output to VSUP, GND or tristate depending of the customer settings as  
    described in Table 3–3 on page 21. Further details can be found in Section 4.8. on  
    page 33.  
    The sensor switches the output to tristate if an overtemperature is detected by the thermal  
    supervision. The sensor switches the output to ground in case of a VSUP wire break and to  
    VSUP in case of a GND wire break.  
    HAL 3711 and HAL 373x indicate a failure by changing the PWM frequency. The  
    different errors are then coded in different duty-cycles.

    In case of undervoltage, the PWM signal will be constantly 'high' or 'low' depending on  
    the setting of bit number 7 in the CUST_SETUP register. Default setting is 'high' level.  
    Note  
    In case of an error, the sensor changes the selected PWM frequency.  
    Example: During normal operation the PWM frequency is 1 kHz, in case of  
    an error 500 Hz.

    3.6. SENT Output  
    The SENT (Single-Edge Nibble Transmission) interface of HAL 373x is implemented  
    according to SAE J2716 release 2010-01.  
    Fig. 3–7 shows the general SENT protocol format. Every transmission starts with a low  
    pulse. The signal is transmitted by the sensor as a series of pulses, whereby the data  
    content is evaluated by time interval between falling edges.  
    The SENT telegram consists of a synchronization/calibration period, a status &  
    communication nibble, three data nibbles, and a CRC nibble and a pause period. See  
    Section 4.8. on page 33 for the timing parameters of a telegram.  
    All timing values in a SENT protocol are referenced to the clock tick time ttick.  
    After reset the output is recessive high. The transmission starts with a low pulse of the  
    synchronization phase (Fig. 3–7). Every low pulse has the same length specified by the  
    parameter tnlow. The synchronization period has always the same length of clock  
    cycles. The clock variation is included in the parameter tsync. The following status and  
    data nibbles always start with a low pulse with tnlow. The nibble high time of the status  
    tstat, the data td3,2,1 and the CRC tcrc depends on the transmitted value. Therefore, the  
    message time of a SENT message depends on the tick time and the value which is  
    transmitted by the message.  
    In order to synchronize the SENT messages to the measurement sampling rate an  
    additional pause period is added, which is transmitted after the checksum nibble.  
    The time to transmit one message is calculated by:  
    tmessage = tsync + tstat + td3 + td2 + td1+ tcrc  
    The checksum nibble is a 4 bit CRC of the data nibbles only. The status & communication  
    nibble is not included in the CRC calculation. The CRC is calculated using polynomial  
    x4+x3+x2+1 with seed value of 5. See SAE J2716 for further CRC implementation details.  
    As recommended by the SAE J2716 an additional zero nibble in addition to the 3 data  
    nibbles for the CRC calculation has been implemented. This is a safety measure  
    against common errors in the last data nibble and the checksum.  
    In HAL 373x the transmitted data nibbles are generated based on the DAC register value.  
    Special data codes have been implemented for error indication via the SENT interface.  
    The angular or linear position information is coded in the signal range from 2 ... 4087 LSB  
    in the 12 bit range. Table 3–5 gives an overview on the data nibble content.  
    HAL 373x is not using the status nibble for additional information transmission.

    Stresses beyond those listed in the “Absolute Maximum Ratings” may cause permanent  
    damage to the device. This is a stress rating only. Functional operation of the device at  
    these conditions is not implied. Exposure to absolute maximum rating conditions for  
    extended periods will affect device reliability.  
    This device contains circuitry to protect the inputs and outputs against damage due to  
    high static voltages or electric fields; however, it is advised that normal precautions be  
    taken to avoid application of any voltage higher than absolute maximum-rated voltages  
    to this high-impedance circuit.

    5. Application Notes  
    5.1. Ambient Temperature  
    Due to the internal power dissipation, the temperature on the silicon chip (junction temper-  
    ature TJ) is higher than the temperature outside the package (ambient temperature TA).  
    TJ = TA + T  
    The maximum ambient temperature is a function of power dissipation, maximum allowable  
    die temperature and junction to ambient thermal resistance (Rthja). With a maximum of 5.5  
    V operating supply voltage the power dissipation P is 0.0825 W per die. The junction to  
    ambient thermal resistance Rthja is specified in Section 4.8. on page 33.  
    The difference between junction and ambient air temperature is expressed by the following  
    equation:  
    At static conditions and continuous operation, the following equation applies:  
    T = P * RthjX  
    The X represents junction to air or case point.  
    Note  
    The calculated self-heating of the device is only valid for the Rth test boards.  
    Depending on the application setup the final results in an application environ-  
    ment might deviate from those values.  
    5.2. EMC and ESD  
    Please contact TDK-Micronas for detailed information on EMC and ESD results.  
    5.3. Application Circuit for HAL 3715 and HAL 372x  
    For EMC protection, it is recommended to connect one ceramic 47 nF capacitor each

    5.5. Measurement of a PWM Output Signal of HAL 3711 & HAL 373x  
    In case of the PWM output, the magnetic field information is coded in the duty cycle of  
    the PWM signal. The duty cycle is defined as the ratio between the high time “s” and the  
    period “d” of the PWM signal (see Fig. 5–4).  
    Note  
    The PWM signal is updated with the rising edge. Hence, for signal evaluation,  
    the trigger-level must be the rising edge of the PWM signal.

    6. Programming of the Sensor  
    HAL 37xy features two different customer modes. In Application Mode the sensors  
    provide a ratiometric analog output voltage or a digital output signal (PWM or SENT). In  
    Programming Mode it is possible to change the register settings of the sensor.  
    After power-up the sensor is always operating in the Application Mode. It is switched  
    to the Programming Mode by a pulse at the sensor output pin.  
    6.1. Programming Interface  
    In Programming Mode HAL 37xy is addressed by modulating a serial telegram on the  
    sensors output pin. Both sensors answer with a modulation of the output voltage.  
    A logical “0” is coded as no level change within the bit time. A logical “1” is coded as a level  
    change of typically 50% of the bit time. After each bit, a level change occurs (see Fig. 6–1).  
    The serial telegram is used to transmit the EEPROM content, error codes and digital  
    values of the angle information from and to the sensor.

    6.2. Programming Environment and Tools  
    For the programming of HAL 37xy during product development a programming tool includ-  
    ing hardware and software is available on request. It is recommended to use the Micronas  
    tool kit (USB kit and Lab View Programming Environment) in order to facilitate the product  
    development. The details of programming sequences are also available on request.

    6.3. Programming Information  
    For production and qualification tests, it is mandatory to set the LOCK bit to one and the  
    POUT bit to zero after final adjustment and programming of HAL 37xy.  
    Before locking the device, it is recommended to read back all register values to ensure  
    that the intended data is correctly stored in the sensor’s memory. Alternatively, it is also  
    possible to cross-check the sensor output signal with the intended output behavior.  
    The success of the LOCK process shall be checked by reading the status of the LOCK  
    bit after locking.  
    It is also mandatory to check the acknowledge (first and second) of the sensor after each  
    write and store sequence to verify if the programming of the sensor was successful. Addi-  
    tionally it is mandatory to set the Diagnosis Latch bit to ensure that programming errors are  
    indicated by the second acknowledge. Additionally, CLAMP-LOW must be set to 100% in  
    case of HAL 3711 and HAL 373x. This bit must be set back to zero to avoid unintended  
    error indication during normal operation of the device. To enable debugging of the produc-  
    tion line, it is recommended to read back the PROG_DIAGNOSIS register and the  
    DIAGNOSIS register in case of a missing second acknowledge. Please check  
    HAL/HAR 37xy Programming Guide for further details.  
    Electrostatic Discharges (ESD) may disturb the programming pulses. Please take pre-  
    cautions against ESD.  
    Note  
    Please check also the “HAL 37xy, HAR 37xy User Manual” and relevant  
    documentation for the USB-Kit. It contains additional information and instruc-  
    tions about the programming of the devices.
