Mobile terminal and method for protecting charging

Abstract

The invention discloses a charging protection mobile terminal and a method of the charging protection mobile terminal. The mobile terminal comprises a charger module, a charging current detection module, a central processing unit, a power management module, a charging current control module, an emitter follower module and a current amplification module. The charger module is used for outputting a first charging current; the charging current detection module is used for receiving the first charging current of the charger module and detecting the intensity of the first charging current; the central processing unit is used for receiving signals and transmitting control signals; the power management module is used for receiving the first charging current output by the charger module and charging the terminal; when the current is larger than a preset value, the charging current control module is started by receiving the control signals transmitted by the central processing unit, and the first charging current is reduced to a second charging current; the emitter follower module is used for conducting noise reduction on the second charging current; the current amplification module is started by receiving a third charging current obtained after noise reduction of the emitter follower module, transmitting an interrupt signal to the central processing unit and receiving second control signals transmitted by the central processing unit.

Description

technical field [0001] The invention relates to the field of charging of mobile terminals, in particular to a mobile terminal for protecting charging and a method thereof. Background technique [0002] With the development of smart mobile terminals, more and more users begin to accept the different user experience brought by the technology of smart mobile terminals. In addition to being the most basic communication tool, the powerful application functions of smart mobile terminals make users more and more inseparable from it. For example, many users cannot do without their mobile phones when they are charging, such as sending text messages, making phone calls, playing games, browsing the web, and reading e-books. These operations consume a lot of battery power of the smart mobile terminal, but due to the limitation of the overvoltage protection unit inside the power management module, for example, the charging current is less than 1A, the overvoltage protection unit inside ...
