Problems solved by technology

When there is an abnormal state on the access module connecting the power supply module and the terminal system circuit, such as foreign objects on the access module, or poor contact of some lines on the access module, it is easy to cause the channel impedance of the access module to be too high, and the resistance heat consumption is too high. High lead to burn-in phenomenon, reducing the security of mobile terminals

Abstract

The embodiment of the invention discloses a power supply control method, a system module and a mobile terminal. The method comprises following steps of determining access impedance of an access module in the mobile terminal, wherein the access module is located between a power supply module and the system module in the mobile terminal; judging whether the access impedance is greater than a preset impedance threshold value or not; controlling an access switch in the access module to be in a switch-off state if the access impedance is greater than the preset impedance threshold value, thus stopping the power supply module from supplying power to the system module. According to the embodiment of the invention, the power supplied to the system module of the mobile terminal can be stopped timely by detecting whether the access impedance is abnormal or not; the burnout phenomenon is avoided; and the security of the mobile terminal is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a power supply control method, a system module and a mobile terminal. Background technique [0002] At present, mobile terminals have gradually become an indispensable demand in users' lives, and users carry mobile terminals with them, which has higher requirements on the security performance of mobile terminals. The circuit structure of a mobile terminal generally includes a power supply module, a terminal system circuit, and a path module connecting the power supply module and the terminal system circuit. Wherein, the power supply module may include a power supply battery, etc., and the terminal system circuit may include a module circuit for realizing various functions of the mobile terminal. When there is an abnormal state on the access module connecting the power supply module and the terminal system circuit, such as foreign objects on the access module, or poor co...
