Disclosed herein is a battery protection circuit module device. The battery protection circuit module device includes a charging unit, a battery protection circuit module, and a system. The charging unit includes first and second MOSFET switches, and supplies externally input power to a battery or a system. The battery protection circuit module includes the battery, third and fourth MOSFET switches configured to be selectively turned on and off, a resistor and a capacitor configured to supply the voltage of the battery to the PCM controller as driving power, and the PCM controller configured to control the third and fourth MOSFET switches. The system is operated using the voltage of the battery or externally input voltage. The third and fourth MOSFET switches of the battery protection circuit module are connected via a common drain structure and a common drain terminal is connected to an internal ground.
