Abstract

The invention discloses a multi-protocol fast charging adapter and an adaptation method. The fast charging adapter comprises an operational amplifier module, an RC low-pass filter module, a master control MCU, an LDO power supply module, a multi-protocol chip, a multi-protocol collection resistance network and a TYPE-C interface, wherein the operational amplifier module is connected to the mastercontrol MCU after being connected to the RC low-pass filter module, and the multi-protocol chip is connected to the multi-protocol collection resistance network and is connected to the master controlMCU through the multi-protocol collection resistance network. After the TYPE-C interface detects the access of a device, the master control MCU sends a signal to the access device, meanwhile the multi-protocol chip performs other fast charging protocol handshake excluding the PD protocol with the access device to identify and judge the type of the access device so as to achieve a fast charging effect.

Description

technical field [0001] The invention belongs to the technical field of adapters, in particular to a multi-protocol compatible fast charging adapter and method. Background technique [0002] As the power consumption of consumer electronic products becomes more and more serious, but the development of battery technology is limited by the chemical system and structural limitations, it is difficult to quickly make a breakthrough in the energy density of lithium polymer batteries, and fast charging technology has become the best for "curve to save the country". Program. Therefore, there are various fast charging protocols on the market, such as Qualcomm protocol, MTK protocol, Huawei protocol, OPPO&VIVO protocol, Samsung protocol, PD protocol and so on. [0003] Although the USB-IF organization has specified that the new version of the USB interface will not allow voltage adjustment through non-USB-PD protocols, Google also emphasized in the Android 7.0 OEM specification that fa...
