Claim 5:
6. The method of claim 5, wherein the overcurrent detection step comprises:
a charge overcurrent detection step of detecting overcurrent due to overcharge according to the comparison result during charge by comparing a voltage at both ends of the sensing resistor of the power management unit of the external system, which is sensed through the overcurrent sensing step, with a predetermined reference charge overcurrent blocking voltage value; and
a discharge overcurrent detection step of detecting overcurrent by overdischarge according to the comparison result during discharge by comparing a voltage at both ends of the sensing resistor of the power management unit of the external system, which is sensed through the overcurrent sensing step, with a predetermined reference discharge overcurrent blocking voltage value.
