Abstract
Disclosed is an over-voltage protection device in a portable equipment. The device comprises an over-voltage detection signal generating unit for detecting over-voltage from power being applied from an external equipment and outputting an over-voltage detection signal; an over-voltage interruption unit controlled by the over-voltage detection signal of the over-voltage signal generating unit and determining whether the applied power should be supplied to a main circuit or not; and an over-voltage and backflow current interruption unit for transferring or interrupting power being applied to the main circuit and interrupting current flowing backward from the battery, depending on the determination of the over-voltage interruption unit.
