  • Publication number: 20090184688
    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.
