Abstract
A portable electronic device is provided. Connector includes the first and data pins. Processor includes input and output pins and detection pin coupled to the input pin. First resistor is coupled between the detection pin and first voltage. When the processor detects that the first and second pins of charger are coupled to the first and second data pins of the connector, the processor provides switching signal to the selector, so as to couple the first and second data pins of the connector to the input and output pins of the processor, respectively, and to provide second voltage different from the first voltage, to the second pin of the charger via the output pin. The processor obtains charging current value of the charger according to voltage of the detection pin. The charger includes second resistor coupled between the first and second pins.
