HALL-EFFECT SWITCH

The A3240-- Hall-effect switch is an extremely temperature-stable

and stress-resistant sensor especially suited for operation over extended

temperature ranges to +150°C. Superior high-temperature performance

is made possible through dynamic offset cancellation, which reduces the

residual offset voltage normally caused by device overmolding, tempera-

ture dependencies, and thermal stress.

Suffix ‘–LT’ & ‘–UA’ Pinning

(SOT89/TO-243AA & ultra-min SIP)

PTCT

The device includes on a single silicon chip a voltage regulator,

Hall-voltage generator, small-signal amplifier, chopper stabilization,

Schmitt trigger, and a short-circuit protected open-collector output to

sink up to 25 mA. A south pole of sufficient strength will turn the

output on. An on-board regulator permits operation with supply voltages

of 4.2 to 24 volts.

The first character of the part number suffix determines the device

operating temperature range; suffix ‘E–’ is for -40°C to +85°C and

‘L–’ is -40°C to +150°C. Three package styles provide a magnetically

optimized package for most applications. Suffix ‘–LH’ is a modified

SOT23W surface-mount package, ‘–LT’ is a miniature SOT89/TO-

243AA transistor package for surface-mount applications; while suffix

‘–UA’ is a three-lead ultra-mini-SIP for through-hole mounting.

HALL-EFFECT SWITCH

FUNCTIONAL DESCRIPTION

Chopper-Stabilized Technique. The Hall element can be

REG

considered as a resistor array similar to a Wheatstone bridge. A

large portion of the offset is a result of the mismatching of these

resistors. These devices use a proprietary dynamic offset

cancellation technique, with an internal high-frequency clock to

reduce the residual offset voltage of the Hall element that is

normally caused by device overmolding, temperature dependen-

cies, and thermal stress. The chopper-stabilizing technique

cancels the mismatching of the resistor circuit by changing the

direction of the current flowing through the Hall plate using

CMOS switches and Hall voltage measurement taps, while

maintaing the Hall-voltage signal that is induced by the external

magnetic flux. The signal is then captured by a sample-and-

hold circuit and further processed using low-offset bipolar

circuitry. This technique produces devices that have an

extremely stable quiescent Hall output voltage, are immune to

thermal stress, and have precise recoverability after temperature

cycling. This technique will also slightly degrade the device

output repeatability. A relatively high sampling frequency is

used in order that faster signals can be processed.

VOLTAGE

Dwg. AH-011-2

More detailed descriptions of the circuit operation can be

found in: Technical Paper STP 97-10, Monolithic Magnetic

Hall Sensor Using Dynamic Quadrature Offset Cancellation

and Technical Paper STP 99-1, Chopper-Stabilized Amplifiers

With A Track-and-Hold Signal Demodulator.

Operation. The output of these devices switches low (turns

on) when a magnetic field (south pole) perpendicular to the Hall

sensor exceeds the operate point threshold (B_OP). After turn-on,

the output is capable of sinking 25 mA and the output voltage is

V_OUT(SAT). When the magnetic field is reduced below the

release point (B_RP), the device output goes high (turns off). The

difference in the magnetic operate and release points is the

hysteresis (B_hys) of the device. This built-in hysteresis allows

clean switching of the output even in the presence of external

mechanical vibration and electrical noise.

OUT(SAT)

Applications. It is strongly recommended that an external

bypass capacitor be connected (in close proximity to the Hall

sensor) between the supply and ground of the device to reduce

both external noise and noise generated by the chopper-

stabilization technique.

The simplest form of magnet that will operate these devices

is a ring magnet. Other methods of operation, such as linear

magnets, are possible. Extensive applications information on
