INTERFACE SUPPLY CIRCUIT
First Claim
1. An interface supply circuit comprising:
- a control circuit couplable to an interface;
a power supply configured to supply power to the interface;
a control chip coupled to the power supply, anda detection chip coupled to the control chip;
wherein the interface is configured to receive a wireless card;
wherein the detection chip is configured to detect a working state of a computer and detect whether the wireless card is inserted into the interface;
wherein the detection chip is configured to send a stop signal to the control chip upon detecting that the computer is shutdown and that the wireless card is not inserted into the interface;
wherein the control chip is configured to send a disconnect signal to the control circuit upon receiving the stop signal, andwherein the control circuit is configured to disconnect the power supply and the interface upon receiving the disconnect signal.

Abstract
An interface supply circuit includes an interface, a control circuit coupled to the interface, a power supply coupled to the control circuit, a control chip coupled to the power supply, and a detection chip coupled to the control chip and the interface. The power supply supplies power to the interface. The interface is configured to receive a wireless card. The detection chip is configured to detect a working state of a computer and detect whether the wireless card is inserted into the interface. The detection chip sends a stop signal to the control chip upon detecting that the computer is shutdown and that no wireless card is inserted into the interface. The control chip sends a disconnect signal to the control circuit upon receiving the stop signal. The control circuit disconnects the power supply and the interface upon receiving the disconnect signal.
