Problems solved by technology

Due to the existence of excessive use of lamps, that is, excessive battery consumption, this will lead to over-discharge of the battery, resulting in shortened battery life, which will shorten the service life of the lamp
Increased cost of use and replacement of lamps
Especially in occasions where this type of lamp is required, if the lamp cannot be used normally at an important moment due to over-discharge of the battery, it may cause unpredictable losses
In addition, other scenes that need to use battery power also have similar battery over-discharge problems

Abstract

The embodiment of the invention discloses a protection circuit comprising an amplifier module, a comparison module, and a switch module. The amplifier module connected with an anode of a battery is used for amplifying the voltage of the battery and outputting the voltage; the comparison module is respectively connected with the amplifier module and the anode of the battery and is used for generating a reference voltage based on the output voltage of the amplifier module, comparing the reference voltage with the voltage of the battery, and outputting a corresponding level signal; and the switch module connected with the comparison module is used for receiving the level signal and controlling the loop opening of the battery to protect the battery. With the protection circuit, the battery can be protected, thereby avoiding over discharge of the battery; and thus stability of the lamp during application can be improved and the service lives of the battery and the lamp can be prolonged.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a protection circuit. Background technique [0002] The stability and life of lamps are very important, and have a very important impact on people's daily life and work. For lamps powered by batteries, the battery life is an important indicator to measure the overall stability and life of the lamp. Due to the excessive use of the lamp, that is, the excessive consumption of the battery, this will cause the battery to be over-discharged, resulting in a shortened life of the battery and a shortened service life of the lamp. The use cost and replacement cost of lamps increase. Especially in occasions where this kind of lamp is required, if the lamp cannot be used normally at an important moment due to over-discharge of the battery, it may cause unpredictable losses. In addition, other scenarios that require battery power also have similar battery over-discharge problems. Contents of t...
