Functional Description : WSH130 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. Features: ● Operates from 2.4V to 26V supply voltage with reverse voltage protection ● Operates with magnetic fields from DC to 15kHz ● On-chip Hall Sensor ● 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, and DC brushless motors
