Functional Description :
WSH1132 is designed to integrate Hall sensor with output driver together on the same chip, it is suitable for speed measurement, revolution counting, positioning. It includes a temperature compensated voltage regulator, a differential amplifier, a Hysteresis controller and a output driver capable of sinking up to 20mA current load. An on-chip protection resistor is implemented to prevent reverse power fault.

FEATUREs:
● Operates from 2.4V to 20V supply voltage
● Operates with magnetic fields from DC to 15kHz
● On-chip Hall Sensor and pull-high resistor
● On-chip temperature compensation circuitry minimizes shifts in on and off points
   and hysteresis over temperature and supply voltage
● Ideal sensor for speed measurement, revolution counting, positioning
● Off (High) with magnetic North pole and On (Low) without magnetic field or
   with magnetic South pole
