摘要： A secondary-battery protection circuit is configured to, in response to detecting that a first switching circuit is turned on and a second switching circuit is turned on, supply a first output voltage to a first load between a first terminal and a second terminal; and supply a third output voltage to a second load between the first terminal and a third terminal, the third output voltage indicating the sum of the first output voltage and a second output voltage, the second output voltage corresponding to a voltage across a second secondary battery. In response to detecting that the first switching circuit is turned off and the second switching circuit is turned on, the secondary-battery protection circuit is configured to stop supplying the first output voltage to the first load; and stop supplying the third output voltage via the first terminal and the third terminal.

摘要： A plug with a cable includes a plug and a cable. The plug is connected to a receptacle to which a secondary cell is connected. The plug includes a housing and a substrate therein. The cable includes a power supply line and a grounding line. The cable has one end connected to the plug and the other end connected to a power supply unit. A switch is mounted on the substrate and provided in series in a power supply interconnection connected to the power supply line. A temperature sensor is mounted on the substrate and disposed near a power supply terminal or a grounding terminal of the plug. A control circuit is mounted on the substrate and configured to interrupt the power supply interconnection by turning off the switch when a temperature detected by the temperature sensor exceeds a predetermined value.
