Abstract
A disclosed battery protecting circuit includes a battery protecting IC powered by a voltage of a secondary battery; another battery protecting IC powered by a voltage of another secondary battery connected to the secondary battery in series; and a constant voltage output unit which receives a maximum voltage obtained by adding voltages of the secondary battery and the other secondary battery in series and outputs a constant voltage upon receipt of a control signal from an output terminal of the battery protecting IC or the other battery protecting IC.
