CIRCUIT DEVICE FOR PROTECTING BATTERY

A battery protection circuit (100) device includes: a first voltage distribution circuit (110) that connects to positive (C+) and negative charger terminals (C-), and configured to distribute a charging voltage of the charger; a first FET (130) that connects between a battery (200) and the positive terminal (C+) to receive a charging current from the charger and supply the charging current to the battery (200), the first FET (130) being connected to a first node (n1) of the first voltage distribution circuit (110), and controlled based on a magnitude of the charging voltage; a second voltage distribution circuit (150) that connects to the positive (C+) and negative terminals (C-), and configured to distribute the charging voltage; and a second FET (170) that connects to the positive terminal (C+), the second FET (170) being connected to the first node (n1) and a second node (n2) of the second voltage distribution circuit (150), and turned on or off based on the magnitude of the charging voltage.
