Claim 3:
4. The circuit according to claim 1, wherein the wake-up circuit comprises:
a wake-up function enabling circuit configured to communicate the detection point with the wake-up circuit when the plug is connected to the socket;
a delay circuit configured to implement delayed conduction of a switching transistor;
a trigger level conversion circuit configured to trigger a wake-up signal output circuit to output the wake-up signal when the resistance value of the connected resistor of the plug status detection circuit is less than a first resistance value and the switching transistor in the delay circuit is switched off, and trigger the wake-up signal output circuit to output the wake-up signal when the resistance value of the connected resistor of the plug status detection circuit is greater than a second resistance value and the switching transistor in the delay circuit is switched on; and
the wake-up signal output circuit is configured to output the wake-up signal under the trigger of the trigger level conversion circuit.
