Abstract

The invention relates to an interface power supply system, which comprises a conversion power supply, a control chip and a control circuit, wherein the control circuit connects the conversion power supply and the control chip; the conversion power supply is used for supplying electricity to an interface; the control circuit is switched on and outputs a detection signal to the control chip when the short circuit condition occurs between the conversion power supply and the interface; and the control chip is used for cutting off the electricity supply to the interface after receiving the detection signal.

Description

technical field [0001] The invention relates to an interface power supply system. Background technique [0002] PCH (PlatformControllerHub) is an integrated south bridge, which has all the functions of the original ICH (Input / OutputControllerHub) and the management engine function of the original MCH (MemoryControllerHub) chip. When the PCH detects that the power supply of the USB (UniversalSerialBus, Universal Serial Bus) interface has an overcurrent abnormality, it will control the power supply to the USB interface, thereby protecting the circuit. However, a small card (DaughterBoard) is installed on the current motherboard, and the small card includes multiple USB interfaces. When the power supply supplies power to the USB interfaces of different small cards, when a short circuit occurs between multiple USB interfaces and the power supply, the PCH will make a misjudgment, thereby damaging the circuit. Contents of the invention [0003] In view of the above, it is nece...
