The invention relates to an emergency battery protection and emergency indicating lamp circuit which comprises a charging IC, a battery reverse connection protection circuit, a battery full charge detection circuit and a battery pull-out or fault detection circuit. When the battery is not reversely connected, the BAT pin of the charging IC is connected with the positive electrode of the battery bythe battery reverse connection protection circuit, and the battery is normally charged; when the battery is reversely connected, the battery reverse connection circuit disconnects the BAT pin of thecharging IC from the positive electrode of the battery, and the battery is not charged; when the battery is fully charged, the CHRG pin of the charging IC is pulled to a low level by the battery fully-charged detection circuit, and the indicating lamp of which the cathode is connected with the CHRG pin is lightened; and when the battery is pulled out, the battery is pulled out or the fault detection circuit disconnects the positive electrode of the indicating lamp from the input power supply VIN, and the indicating lamp is turned off. The emergency battery protection and emergency indicating lamp circuit meets the requirements of safety certification.
Description
technical field [0001] The invention relates to a charging circuit, in particular to a battery protection and indicator light circuit. Background technique [0002] The traditional emergency light indicator circuit lights up after charging, turns off when fully charged, and turns off when the battery fails. In this way, it is impossible to distinguish between the two states of full charge and failure, which does not meet the requirements of safety certification. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide an emergency battery protection and emergency indicator circuit, which meets the requirements of safety certification. [0004] In order to solve the above-mentioned technical problems, the present invention provides an emergency battery protection and emergency indicator circuit, including: a charging IC, a battery reverse connection protection circuit, a fully charged battery detection circuit, and a ...
