Abstract
The present invention relates to a battery protection circuit and a method for protecting the battery protection circuit in which instead of connecting the charge/discharge FET on the current path between the battery and the external system, when an abnormal condition occurs in the battery, the 0V voltage of the battery cell is transmitted to the external system through the disconnection of the voltage sensing line to cut off the abnormal current of the battery in the external system.
