Abstract

The invention discloses a data line and charging equipment, and belongs to the technical field of communication. The data line comprises a Type-A interface and a Type-C interface. VBUS pins, communication pins and GND pins in the first Type-A interface and the Type-C interface are connected in a one-to-one correspondence mode, and when the data line is connected with a first charger, a first switching circuit in the data line controls a CC pin in the first Type-A interface to be communicated with a CC pin in the Type-C interface; and when the data line is connected with a second charger, the first switching circuit controls the CC pin in the first Type-A interface to be disconnected from the CC pin in the Type-C interface, and the CC pin in the Type-C interface is connected with the VBUS pin. According to the embodiment of the invention, the PD charging function can be realized through the CC pins when the data line is connected with the first charger.

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 to quickly charge devices such as notebook computers. In order to support PD protocol charging, the charger needs to use CC signal lines for communication. The charger supporting PD protocol charging usually Adopt the third standard (Type-C) interface, and match the data line of Type-C to Type-C. For the data line using the first standard (Type-A or Standard-A) interface, since it does not have a connected CC line, it does not support PD charging. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a data cable and a charging device, ...
