Abstract
A controller includes: a transmission terminal, operable for transmitting a clock signal transmitted by an external device, and also operable for receiving electric power supplied by a power source to enable the controller to generate a voltage signal; a processing unit, coupled to the transmission terminal, operable for performing a logical operation on the voltage signal and generating an indication signal based on the clock signal, the indication signal includes a rectangular wave signal having a first level and a second level; and a feedback unit, coupled to the processing unit, operable for providing a configuration signal indicating a type of the charging cable when the indication signal is changed from a second level to a first level. The transmission terminal transmits the configuration signal to the external device, to enable the external device to identify the type of the charging cable based on the configuration signal.
