Zusammenfassung: | The utility model relates to an electronic equipment interface protection circuit and electronic equipment. The electronic equipment interface protection circuit comprises a switch module and a switch control module, the switch module is electrically connected with the switch control module and a first pin and a second pin of the electronic equipment interface respectively; the switch control module outputs a first control signal and a second control signal to the switch module, and the switch module is used for controlling whether the first pin is connected to the wire identification signal or is suspended according to the first control signal and the second control signal. And according to the first control signal and the second control signal, controlling whether the second pin accesses the wire identification signal or is suspended. Through the technical scheme disclosed by the invention, safety accidents of the electronic equipment during large-current charging are avoided, and the corrosion degree of an |
