General Description

: WSH181 is designed to integrate Hall sensor with output driver 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 and a open-collector output driver capable of sinking up to 20mA current load.

An on-chip protection resistor is implemented to prevent reverse power fault.

Overview
