Abstract

The invention relates to a reverse wired charging circuit, a terminal, a reverse wired charging control method and a computer readable storage medium. The reverse wired charging circuit comprises a reverse charging circuit, a data transmission circuit, a connector, a switching circuit and an application processor which are connected through a positive electrode connecting end and a negative electrode connecting end of the reverse wired charging circuit, and a resistor is connected between the positive electrode connecting end and the negative electrode connecting end of the reverse charging circuit in series; the positive electrode connecting end of the data transmission line is connected with the positive electrode connecting end of the application processor, and the negative electrode connecting end of the data transmission line is connected with the negative electrode connecting end of the application processor. According to the method provided by the invention, data transmission and reverse quick charging are separately realized based on the two circuits, and the signal quality during communication transmission can be improved. And the hardware cost is reduced, and the terminalhardware placement space is saved.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to a reverse wired charging circuit, a terminal, a reverse wired charging control method, and a computer-readable storage medium. Background technique [0002] OTG technology is the abbreviation of USB On-The-Go (On-The-Go is portable, meaning on the road, easy to carry on the road), mainly used in the connection between various terminals for data exchange. Terminals include: PDAs, mobile phones, and consumer terminals. When there is no terminal such as a computer, you can directly connect a mobile terminal such as a mobile phone to an external terminal such as a USB flash drive, a card reader, or a digital camera to perform operations such as data transmission or charging. [0003] In related technologies, when one terminal reversely charges another terminal, the maximum external power supply capacity is only 5V / 500mA, and the charging power is 5W. Among...
