The invention provides a power supply protection system and method of a mobile device. The system includes: a charging unit that includes an input terminal connected to the power adapter and the battery, and has an output terminal and an enabling terminal, and is used to output a strobe signal when it is determined that the battery is charged by the power adapter; When the hardware command is started, the charging permission signal is not output, and the corresponding hardware is started with a delay; and when a stop hardware command is detected, the corresponding hardware is stopped, and the charging permission signal is output with a delay; The output terminal of the processing unit is connected to the two input terminals, and the output terminal is connected to the protection unit of the enabling terminal of the charging unit, which is used to determine whether to output an enabling signal to the enabling terminal to allow charging of the battery by analyzing the signals of the two output terminals; If the enable signal is output, the battery is charged. The invention can prevent the current impact on the charging circuit caused by the hardware starting and stopping during the process of charging the battery by the power adapter.
Description
technical field [0001] The invention relates to a power protection technology, in particular to a power protection system and method for mobile equipment. Background technique [0002] With the intelligentization of mobile phones, mobile phones bring people a convenient lifestyle, and many functions are integrated into mobile phones. Such as online shopping, games, and Internet of Things control functions through mobile phones and other controlled electronic devices. A mobile phone is no longer just for calling and sending text messages as it used to be. This will inevitably require the phone to have a long battery life. People often use mobile devices such as mobile phones while charging. [0003] Using a mobile device while charging will increase the power consumption of its charging circuit, and the direct negative result is that the phone becomes hot. The internal integrated chip is often in the limit working state. The long-term heat loss coupled with the impact of ...
