描述 Description

WT7507 is a switching power supervisor for PC or Server System. It provides over/under voltage detection, over-current detection, over temperature detection, power good detection, power good output (PGO), fault protection latch output (FPOB), and PSONB control. The Over Temperature Protection circuit senses the input voltage of OTP pin. If OTP pin is higher than the HIGH threshold, FPOB pin goes to high impedance to shut down the power supply. When the OTP pin goes lower than LOW threshold, FPOB pin is low and restarts power supply automatically. WT7507-165/167 has FAN control function. Fan speed can be controlled by the FC input pin and PWM output pin.
