Abstract

The invention relates to the technical field of charging, in particular to an OTG power supply and wireless charging compatible circuit, a related method and a terminal device. A switch module is arranged so that when the terminal device is determined to perform wireless charging, an OTG device is connected at the same, the switch module is controlled to enable a wireless reception module to be electrically connected to a charging circuit of a battery module and a wired interface module and to enable the wired interface module to be disconnected with the charging circuit, thereby enabling thewireless reception module to supply electric energy to the charging circuit and the OTG device at the same time. Therefore, wireless charging and the OTG function of the terminal device can be performed at the same time.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to an OTG power supply and wireless charging compatible circuit, a related method, and a terminal device. Background technique [0002] OTG is the abbreviation of On-The-Go, which is mainly used in the connection and data transmission between various devices without a Host. For example, based on OTG technology, a digital camera can be directly connected to a printer through the USB (Universal Serial Bus, Universal Serial Bus) interfaces of two devices to print out the photos taken; The data is sent to the mobile hard disk, so that it is no longer necessary to carry an expensive digital camera memory card or a laptop used as a Host when working in the field. In addition, based on OTG technology, it is also possible to expand the USB interface accessories of the smart terminal to enrich the functions of the smart terminal; for example, to expand the remote control accessories, the s...
