Hall Effect Sensor IC With Thermal Lock Protection And Auto Restart Function

WSH413 is designed to integrate Hall Sensor with complementary output drivers and frequency generator 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, two Darlington output drivers capable of sinking 500mA current load and an PWM signal input pin capable of doing speed control. An on-chip Protection Diode is implemented to prevent reverse power fault. And built-in thermal lock protection and auto-restart function is suitable for super high speed fan. It CAN replace the function of lock protection and auto restart function. The power will be shutdown automatically at 125C to prevent the coils be damaged and auto-restart after cooling down 5~10C when thermal protected was activated . By Winson Semiconductor Corp.
