Abstract
A system that detects electrical disconnection of one connector from another connector includes a detection circuitry and a protection circuitry. The detection circuitry detects that a plug connector has been electrically disconnected from a corresponding receptacle connector. In response to the detection, the detection circuitry sends a signal to the protection circuitry. In response to the signal, the protection circuitry lowers or terminates power being supplied to a host device via one of the contacts of the plug connector. This helps to prevent shocks/shorts that may be caused by accidental disconnection of the plug connector.
