Abstract: An apparatus for controlling power of a mobile terminal is provided. The apparatus includes a power conversion for providing a ground connection during a time interval if a power value is input for testing the mobile terminal and a power control unit having one terminal for controlling the power of the mobile terminal wherein, if the given power value is grounded during the time interval and a voltage level required to control power of the mobile terminal changes, the power control unit turns on power to the mobile terminal.

Abstract: A charging apparatus and method for a mobile terminal are provided. The apparatus and method charge a battery by identifying a charger and operating in an operation mode corresponding to the identified charger. If the mobile terminal is connected to a charger via an outer connector in order to charge the internal power source of the mobile terminal, power and a configuration signal are input from the charger, a logic characteristic is output by using the received configuration signal, and thus the charger can be exactly identified according to the power and the configuration signal. Also, since the internal power source of the mobile terminal is charged through the exactly identified charger, the internal circuit of the mobile terminal or battery can be prevented from being damaged by unstable power of the charger.
