Pcm with novel structure and battery pack including the same

PURPOSE: A protection circuit module is provided to precisely perform detection for current value and high temperature and to minimize the number of components. CONSTITUTION: A protection circuit module(102) for protecting a secondary battery from overcharging, overdischarging, charge excess current and discharge excess current includes: a protection integrated circuit(212) for accumulating an over charge detection circuit, an over discharge detection circuit, a charge overcurrent detection circuit, and a discharge overcurrent detection circuit; a FET device(230) for recharge control which is off when overcharging or charge excess current is detected; a FET device(220) for discharge control; and an NTC thermistor(240).
