DATA LINE AND CHARGING DEVICE

A data cable and a charging device belong to the field of communication technologies. The data cable includes a type-A interface (1) and a type-C interface (2), and the type-A interface (1) and the type-C interface (2) each include a VBUS pin, a CC pin, a D+ pin, a D- pin, and a GND pin. A circuit identification module (4) is disposed in the data cable, and the circuit identification module (4) includes a switch circuit (42), a filtering circuit (43), a voltage regulator circuit (41), and a comparator circuit (44). The switch circuit (42) is connected to a CC pin of the type-C interface (2), an output terminal of the voltage regulator circuit (41), a CC pin of the type-A interface (1), and an output terminal of the comparator circuit (44). Under the control of the comparator circuit (44), the switch circuit (42) connects the CC pin of the type-C interface (2) to the CC pin of the type-A interface (1) or the output terminal of the voltage regulator circuit (41).
