Abstract
A protective circuit module for a secondary battery is provided including a circuit board. At least one protection control circuit element for preventing overcharge and over-discharge of the secondary battery is mounted on the circuit board. A first conductive pad is coupled to the circuit board. A positive temperature coefficient device is between the at least one protection control circuit and the first conductive pad such that when a secondary battery temperature reaches a threshold value, resistance of the positive temperature coefficient device is increased and battery current is reduced.
