Abstract
A battery protection circuit and a method of controlling the same is disclosed. The battery protection circuit includes: a battery management system for controlling charging and discharging of a battery; and a reset control circuit for controlling a reset operation of the battery management system. The battery management system includes: a reset terminal to which a first voltage for determining reset is applied; and a reset prevention terminal to which a second voltage for determining reset prevention of the battery management system is applied. The reset control circuit is connected between the reset terminal and the reset prevention terminal to control the applying of the first voltage to the reset prevention terminal. Accordingly, an unintended reset operation of the battery management system may be prevented.
