WSH132 Description
WSH132 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 pensated voltage regulator, a differential amplifier, a Hysteresis controller and a output driver capable of sinking up to 20 mA current load. An on-chip protection resistor is implemented to prevent reverse power fault.
