Electrical path management circuit, electrical path management chip and electronic equipment

Abstract

The invention discloses an electrical path management circuit, an electrical path management chip and electronic equipment. The electrical path management circuit comprises a first switching circuit, a second switching circuit, a first power switching circuit, a third switching circuit, a second power switching circuit and a fourth switching circuit, the first switch circuit and the second switch circuit are used for externally connecting a first power supply and a second power supply to respectively receive a first power supply signal and a second power supply signal input by the first power supply and the second power supply; the first power switch circuit is used for externally connecting positive and negative electrodes of a first rechargeable battery; the second power switch circuit is used for externally connecting positive and negative electrodes of a second rechargeable battery. Therefore, the electrical path management circuit in the application can automatically adjust the on-off states of the first to fourth switching circuits and the input power supply according to the polarity of the inserted rechargeable battery, so that charging can be carried out without distinguishing the polarity of the battery and through forward insertion and reverse insertion, thereby improving the safety of charging and using the rechargeable battery.

Description

technical field [0001] The present application relates to the technical field of electrical path management, in particular to an electrical path management circuit, an electrical path management chip and electronic equipment. Background technique [0002] Nowadays, because rechargeable batteries have the advantages of large capacity, fast charging speed, easy to carry and use, etc., they have been widely used in people's daily life. [0003] However, there is a problem that rechargeable batteries must be inserted according to the set positive and negative poles before they can be charged, and for some people who know little about this aspect, it is very likely that they will be charged due to wrong polarity when charging. As a result, charging cannot be carried out, and even explosion accidents may occur. Contents of the invention [0004] The application provides an electrical path management circuit, an electrical path management chip, and electronic equipment. The elec...
