A data line and a charging device are provided. The data line includes a Type-A port, a first port, a cable, and a circuit identification module. VBUS pins, D+ pins, D− pins, and GND pins in the Type-A port and the first port are connected in one-to-one correspondence. The circuit identification module includes a pull-up resistor, a switch circuit, and a detection circuit. A first terminal of the switch circuit is connected to the CC pin of the first port, a second terminal is connected to the VBUS pin through the pull-up resistor, a third terminal is connected to the CC pin of the Type-A port, an input terminal of the detection circuit is connected to the CC pin of the Type-A port, and an output terminal is connected to a control terminal of the switch circuit.

Data line and charging device

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.
