Abstract
A battery protection circuit includes a charging switch, a resistor, a charging controller, a switching circuit, a fuse circuit, and a fuse driving circuit. The charging switch is connected to a first electrode of a battery cell. The resistor includes a first end connected to a second electrode of the battery cell. The charging controller supplies a charging control current. The switching circuit connects a second end of the resistor with a control terminal of the charging switch or blocks connection between the second end of the resistor and control terminal of the charging switch depending on the charging control current. The fuse circuit is connected to a charging path of the battery cell and blocks the charging path depending on a voltage applied to a control terminal of the fuse circuit. The fuse driving circuit switches the voltage applied to the control terminal of the fuse circuit depending on a voltage between the ends of the resistor.
