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
● On(L) with magnetic South pole and Off (H) with North pole
