Abstract

The invention discloses a data line and charging device, and belongs to the technical field of communication. The data line comprises a Type-A interface, a first interface and a cable, and the Type-Ainterface is correspondingly connected with a VBUS pin, a D+ pin, a D- pin and a GND pin in the first interface; a circuit identification module is arranged in the data line; and the circuit comprisesa pull-up resistor, a switch circuit and a filter circuit. The first end of the switching circuit is connected with the CC pin of the first interface; the second end is connected with the first end of the pull-up resistor; the third end is connected with a CC pin of the Type-A interface; the second end of the pull-up resistor is connected with the VBUS pin of the first interface, the first end ofthe filter circuit is connected with the CC pin of the Type-A interface, the second end of the filter circuit is connected with the GND pin of the first interface, and the output end of the filter circuit is connected with the control end of the switch circuit; and under the control of the filter circuit, the first end of the switch circuit is communicated with the second end or the third end. According to the embodiment of the invention, the charging device with the Type-A interface can support a PD quick 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 ...
