PORTABLE COMMUNICATION DEVICE AND METHOD FOR CHARGING THROUGH DISCERNMENT OF CHARGING CABLE
First Claim
1. A portable communication device for charging through discernment of a charging cable, the portable communication device comprising:
- a connector for connecting to an external charging device in order to charge a power source in the portable communication device;
a charging unit for charging a battery with power input from the external charging device through the connector; and
a controller for discerning a charging cable by analyzing a current characteristic according to a configuration signal input from the external charging device through the connector, and for controlling the battery to be charged from the external charging device through the discerned charging cable.

Abstract
A portable communication device and method for charging through discernment of a charging cable are provided. When the portable communication device is connected to an external charging device through a connector in order to charge a power source in the portable communication device, a configuration signal is received from the external charging device through a positive data line and a negative data line of the connector, a logic characteristic value is output according to the received configuration signal, the charging cable is discerned by analyzing a current characteristic through connection with a resistance circuit according to the on/off state of a switch which operates according to the logic characteristic value, and a control operation is performed such that a battery is charged from the external charging device through the corresponding charging cable.
