General Description:
WSH41FC is designed to integrate Hall sensor with complementary output drivers and frequency generator together 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 400mA current load and an open-collector frequency generator capable of sinking 10mA current load. An on-chip protection diode is implemented to prevent reverse power fault.

FEATUREs:
● Operate from 2.8V to 20V 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 400mA for driving large load.
● Lower current change rate reduces the peak output voltages during switching.
● Available in rugged low profile SOT-25 , SIP-4L,SIP-5L packages.
● Built-in FG output.
● Built-in protection diode for reverse power supply fault.
