Abstract
A circuit protection apparatus is disclosed. A peripheral interface includes a first power node and a second power node. The circuit protection apparatus includes an auxiliary power supply circuit, a power converter, a first switch, a second switch, a power switch circuit, a warning circuit, and a controller. When a load is plugged to the peripheral interface, the first switch turns on, and the controller is enabled and outputs a control signal, so as to drive the power converter to output power. When the current between input terminal and output terminal of the power switch circuit is larger than a predetermined current, the controller receives the error flag logical voltage outputted by the power switch circuit, cuts off the current between input terminal and output terminal of the power switch circuit, and stops the operations of the power converter.
