Abstract
A data cable and a charging device are provided. The data cable includes a type-A interface and a type-C interface. The type-A interface and the type-C interface each includes a VBUS pin, a CC pin, a D+ pin, a D− pin, and a GND pin. A circuit identification module is disposed in the data cable, and the circuit identification module includes a switch circuit, a filtering circuit, a voltage regulator circuit, and a comparator circuit. The switch circuit is connected to a CC pin of the type-C interface, an output end of the voltage regulator circuit, a CC pin of the type-A interface, and an output end of the comparator circuit. Under the control of the comparator circuit, the switch circuit connects the CC pin of the type-C interface to the CC pin of the type-A interface or the output end of the voltage regulator circuit.
