Abstract: A power control circuit is disclosed. The power control circuit includes a first receiving circuit, a second receiving circuit, a first power supply circuit and a second power supply circuit. The first receiving circuit is electrically connected to a charging circuit and a first port and configured to charge a power unit according to a first port voltage. The second receiving circuit is electrically connected to the charging circuit and a second port and configured to charge the power unit according to a second port voltage. The second receiving circuit is further configured to be disabled according to the first port voltage. The first power supply circuit is configured to supply power to the first port. The second power supply circuit is configured to supply power to the second port. Thus, the power control circuit transmits power or data through different ports.

Abstract: A detection circuit is provided, including a connector and a processing circuit. The connector comprises a first detection terminal and a second detection terminal. The second detection terminal is electrically connected to a first reference potential. The processing circuit is electrically connected to the first detection terminal and is used for receiving a power supply signal. When the connector is connected to a connecting port, the first detection terminal is electrically connected with the second detection terminal through the connecting port to form an electrical loop, so that the processing circuit detects a detection potential on the first detection terminal, and then determines whether the connector is correctly connected to the connecting port.

Abstract: A voltage conversion apparatus includes a power supply circuit with a first switch, a voltage conversion circuit, and a protective circuit with a detection circuit. The first switch transmits a power to generate an input voltage. The voltage conversion circuit generates a first voltage. A second switch of the voltage conversion circuit receives the input voltage. A third switch of the voltage conversion circuit is coupled between the second switch and a ground terminal. The detection circuit generates a first control signal based on the first voltage, a second voltage that corresponds to the first voltage, and a reference voltage. When a voltage value of an error signal is less than the reference voltage, the detection circuit outputs the first control signal to turn off the first switch. The voltage value of the error signal corresponds to a voltage difference between the first voltage and the second voltage.
