WSH415
Hall Effect IC with Two complementary Outputs
Features:
Operate from 2.8V to 28V supply voltage.
On-chip Hall sensor.
Internal bandgap regulator allows temperature compensated operations and a
wide operating voltage range.
High output sinking capability up to
600mA
for driving large load.
Lower current change rate reduces the peak output voltages during switching.
Available in rugged low profile SIP-4L packages.
Built-in protection diode for reverse power supply fault.
General Description:
WSH415 is designed to integrate Hall sensor with two complementary output drivers
on the same chip, it is suitable for speed measurement, revolution counting,
positioning, and DC brushless motors. It includes a temperature compensated voltage
regulator, a differential amplifier, a Hysteresis controller, two open-collector output
drivers capable of sinking 600mA current load. An on-chip protection diode is
implemented to prevent reverse power fault.
The temperature-dependent bias increases the supply voltage of the hall plates and
adjusts the switching points to the decreasing induction of magnets at higher
temperatures. Subsequently, the open collector output switches to the appropriate state.
WSH415 are rated for operation over temperature range from –20˚ C to 100˚C and
voltage ranges from 2.8V to 28V.
