Abstract

The application discloses a data line and a charging device, which belong to the technical field of communication. Wherein, the data line includes the Type-A interface, the first interface and the cable, and the VBUS pin, D+ pin, D-pin and GND pin in the Type-A interface and the first interface are connected correspondingly; There is a circuit identification module, including a pull-up resistor, a switch circuit and a filter circuit. The first end of the switch circuit is connected to the CC pin of the first interface, the second end is connected to the first end of the pull-up resistor, and the third end is connected to the Type The CC pin of the Type-A interface is connected, the second end of the pull-up resistor is connected to the VBUS pin of the first interface, the first end of the filter circuit is connected to the CC pin of the Type-A interface, and the second end of the filter circuit is connected to the CC pin of the Type-A interface. The GND pin of the first interface is connected, and the output terminal of the filter circuit is connected with the control terminal of the switch circuit; wherein, under the control of the filter circuit, the first terminal of the switch circuit is connected with the second terminal or the third terminal. The embodiment of the present application enables a charging device with a Type-A interface to support a PD fast charging function.

Description

technical field [0001] The application belongs to the technical field of communication, and in particular relates to a data line and a charging device. Background technique [0002] With the development of science and technology, the application of fast charging is more and more extensive. [0003] In related technologies, the power delivery (Power Delivery, PD) protocol is usually used for fast charging, and a charger supporting PD protocol charging needs to use a CC signal line for communication. The charger supporting PD protocol charging usually adopts the third standard ( Type-C) interface, and with a Type-C to Type-C data cable. For the data line using the first standard (Type-A or Standard-A) interface, it communicates through the D+ / D- signal line, and cannot support PD protocol charging. However, currently the most widely used data cable is a data cable with a Type-A interface, so that the Type-A interface on a conventional data cable does not support PD protocol ...
