Discharge control circuit, chip, power supply, electronic device of x capacitor

Abstract

The application discloses a discharge control circuit of an X capacitor, a chip, a power supply and an electronic device. The discharge control circuit comprises an alternating current detection module, a discharge control module and a discharge module. The alternating current detection module detects that the alternating current power supply is powered off and lasts for a first preset time, and outputs a power-off signal to the discharge control module. After the discharge control module receives the power-off signal, the discharge control module outputs a conduction signal to the discharge module through a control output end, and the discharge module is turned on to discharge the X capacitor. Through the application scheme, the power-on and power-off of the alternating current can be detected in time, the discharge module is controlled in time by using the discharge control module to discharge and close the discharge, and the safe and loss-saving effect is achieved.
