Abstract
A battery secondary protection circuit includes a first pin, a second pin, a first sensing circuit, a first current source, a first enabling circuit and a first protection circuit. The first pin and the second pin are coupled to two terminals of a first battery. The first sensing circuit, coupled between the first pin and second pin, provides a first sensing signal and a second sensing signal. The first current source, coupled between the first pin and second pin, provides a first current. The first enabling circuit, coupled to the first sensing circuit and first current source, generates a first enabling signal according to the first sensing signal. The first protection circuit is coupled to the first sensing circuit. When the first enabling signal enables the first current source, the first protection circuit generates a first protection signal according to a second sensing signal changed with the first current.
