Single Coil Hall Effect IC With Thermal Lock Protection And Auto-Restart

WSH42FB 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 and an open-collector frequency generator capable of sinking 10mA current load. An on-chip Protection Diode is implemented to prevent reverse power fault. It also includes coil parts. You CAN eliminate all the external components for the function of FG and reverse Protection Diode And built-in thermal lock protection and auto-restart function will automatically shutdown power at 110C to prevent the coils be damaged during high temperature and auto-restart at 105C. It CAN replace the function of lock protection and auto-restart at low cost. By Winson Semiconductor Corp.
