Description

WSH420 is designed to integrate Hall sensor with two push-pull output drivers and frequency generator together on the same chip, it is suitable for single coil DC brushless motors. It includes a temperature compensated voltage regulator, a differential amplifier, a Hysteresis controller, complementary bi-direction drivers for sinking and driving large current load. An on-chip protection resistor is implemented to prevent reverse power fault. And built-in thermal lock protection and auto-restart function will automatically shutdown power at 120 to prevent the coils be damaged during high temperature and auto-restart at 115. It can replace the function of lock protection and auto-restart at low cost.

WSH420 are rated for operation over temperature range from 20 to 85 and voltage ranges from 2.4V to 15V.
