otg device, terminal charging method, mobile terminal and computer-readable storage medium

Abstract

The invention discloses an OTG device, a terminal charging method, a mobile terminal and a computer-readable storage medium. The OTG device includes: an OTG device and a charging device, a USB charging voltage port of the OTG device and a USB charging device of the charging device. The charging voltage port is electrically connected, the ground port of the OTG device is electrically connected to the ground port of the charging device, and the detection positive port and the detection negative port of the charging device are short-circuited. The power management chip in the mobile terminal is used to connect the USB charging voltage to the inside of the mobile terminal when an OTG device is connected to the mobile terminal and the OTG device provides USB charging voltage access, and turn on the step-down circuit And turn off the boost circuit to use the USB charging voltage to charge the battery. The invention realizes the charging of the mobile terminal by the OTG device and the data interaction between the mobile terminal and the OTG device at the same time, thereby improving user experience.

Description

technical field [0001] The present invention relates to the field of mobile terminal control, in particular to an OTG (On The Go, a USB working mode) device, a terminal charging method, a mobile terminal and a computer-readable storage medium. Background technique [0002] Smart mobile terminals have experienced savage growth and have entered the era of deep cultivation in different fields. Major mobile terminal manufacturers are creating their own characteristic attributes, especially in recent years. The popularity of mobile games has accelerated this state, specifically for games The developed mobile terminal, that is, the game mobile terminal, came into being. The mobile terminal elements that online online game users are more concerned about include battery life, network, and heat generation. It is an important factor that affects the experience of mobile game terminals. As network users, we all know that wired networks are more stable than wireless networks, so it is t...

AI Technical Summary

Problems solved by technology

[0003] For charging mobile terminals, users want the charging time to be as short as possible. At present, the application of fast charging technology solutions provided by Qualcomm's platform is quite mature, such as QC2.0, QC3.0, etc. However, during the game There will be a problem: what to do when the user needs both charging and a stable wired network, that is to say, if there is a device that can both charge and connect to the Internet at the same time, this problem can be solved

However, the two-in-one devices for charging and wired Internet access currently on the market can only realize one of the functions at the same time, that is, either charging or wired Internet access.

[0004] Therefore, there is currently no device that supports both charging and mobile terminal wired Internet access in the market.
