Abstract

The invention relates to the technical field of circuit designing, in particular to a self-locking power switch comprising a first MOS (metal oxide semiconductor) transistor, a second MOS transistor, a first triode, a second triode, a third triode, a charger, a battery and other components. System power of an electronic device can be provided through the first MOS transistor by a charger and can also be provided through the second MOS transistor by the battery; a self-locking circuit composed of the first triode and the second triode is capable of effectively controlling reliable connection or disconnection of the electronic device and the battery, power consumption of the battery is maximally reduced, and the self-locking power switch is applicable to various applications, such as remote transporting of electronic equipment.

Description

technical field [0001] The invention relates to the technical field of circuit design, in particular to a power switch with a self-locking function. Background technique [0002] With the development of society, more and more electronic devices, such as mobile phones, pads, game consoles and other electronic products, have non-detachable power supplies, and users can directly charge the power supply and use the electronic devices. [0003] However, products such as electronic equipment have to go through a lot of time and go through various transportation processes from the factory to the user. On the one hand, it is not safe to transport electronic equipment with power on, and it will consume electricity; on the other hand, when the electronic equipment reaches the customer, it may be exhausted due to the power exhaustion, which may cause the electronic equipment to fail to turn on, and it is considered to be a faulty equipment. This wastes a lot of transportation costs an...
