Abstract

The invention discloses a charging circuit and a charging cable, and belongs to the field of charging. The charging circuit comprises a first interface, a second interface, a detection control moduleand a switch module; the first interface outputs a high-level signal through a first signal pin when detecting that the first interface is plugged with a charger compatible with a fast charging protocol; under the condition that the detection control module detects a high level signal, the switch module is controlled to execute preset operation, so thatafirst signal pin and asecond signal pin areconnected, and the ground and abus are disconnected, so that a circuit for common charging is disconnected, electronic equipment can send a quick charging instruction to the first signal pin through the second signal pin, and the charger outputs a quick charging voltage according to the quick charging instruction to charge the electronic equipment.

Description

technical field [0001] The present application belongs to the field of charging, and in particular relates to a charging circuit and a charging cable. Background technique [0002] At present, as the functions of electronic devices become more and more powerful, the standby time of electronic devices will become shorter and shorter; when users pay more and more attention to the length of standby time, the use of fast charging protocols for fast charging solutions (that is, increasing the charging power ) came into being. [0003] At present, the fast charging protocol of electronic devices is usually the PD (Power Delivery) protocol. The fast charging protocol is a standard protocol formulated by the USB_IF organization. The fast charging protocol needs to communicate through the CC signal line in the charging cable. At present, many kinds of notebook computers, Pads, electronic equipment and other products on the market gradually support this protocol; however, the interfa...
