Abstract

The invention discloses a power supply control system and its realization method, comprising: a first input terminal, a second input terminal, an output terminal, a first switch module, a second switch module, a third switch module and a fourth switch module, the first A switch module is connected between the first input terminal and the output terminal, the second switch module is connected between the second input terminal and the output terminal, the third switch module is connected between the first input terminal and the second switch module, and the second switch module is connected between the first input terminal and the second switch module. The four switch modules are connected between the second switch control module and the second switch module. The first switch control module controls the on-off of the first switch module, the third switch module and the fourth switch module, and the second switch control module controls the on-off of the second switch module according to the wake-up signal and the on-off of the fourth switch module, thereby Control the power supply mode of the power control system. Through the above method, seamless switching between the internal power supply and the external power supply can be realized, and mutual power feeding between the external power supply and the internal power supply can be avoided.

Description

technical field [0001] The invention relates to the field of power supply control, in particular to a power supply control system and an implementation method thereof. Background technique [0002] With the development of the Internet and mobile Internet, the requirements for network security are gradually increasing. The third-generation USB KEY technology that integrates RTC (Real-time communication) technology and second-generation USB KEY technology has higher security. However, this technology has problems in power switching control, that is, it does not support seamless switching between battery power supply and external interface power supply, and cannot wake up when the battery is powered. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a power supply control system and its implementation method, which can realize seamless switching between the internal power supply and the external power supply, avoid m...
