    • 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.
    • 公开了一种电路保护装置。 外围接口包括第一功率节点和第二功率节点。 电路保护装置包括辅助电源电路,功率转换器,第一开关,第二开关,电源开关电路,警告电路和控制器。 当负载插入外围接口时,第一个开关打开,控制器被使能并输出一个控制信号,以驱动电源转换器输出电源。 当电源开关电路的输入端子和输出端子之间的电流大于预定电流时,控制器接收由电源开关电路输出的误差标志逻辑电压,切断电源开关的输入端子和输出端子之间的电流 电路,停止电源转换器的运行。
