Title:
MULTI-FAST CHARGING PROTOCOL CONTROL CIRCUIT, CONTROL METHOD, CHIP, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/214083
Kind Code:
A1
Abstract:
The present application provides a multi-fast charging protocol control circuit, comprising a charging logic control module, a first voltage measurement module, a second voltage measurement module, an AFSCP sending module, a VOOC sending module, a DP interface, a DM interface, a VBUS interface, a GND interface, a timer module, a switch G1, a switch G2, and a switch G3. The charging logic control module is configured to control the voltage measurement modules to measure voltages of the DP interface and the DM interface, to perform timing by means of the timer module, to control the on/off of the switches according to the voltage measurement results, the timing result and the current of the VBUS interface, to communicate with a load device using a corresponding communication protocol, and to charge the load device by means of the VBUS interface. The multi-fast charging protocol control circuit provided by the present application can realize the fast charging of a plurality of fast charging protocols, can implement the supporting of a plurality of fast charging protocols by a single chip when applied to a fast charging protocol chip, is flexible in application, and reduces cost.
