A power supply circuit in an electronic device is provided. The power supply circuit includes a connector configured to receive external power and IDentifier (ID) data, a first switch disposed between the connector and a system of the electronic device, a second switch connected to the system, and a controller configured to control ON and OFF states of each of the first and second switches based on the ID data.

Power supply circuit in electronic device and control method thereof

Provided is a method and apparatus for identifying a type of an external device connected to an interface connector in an electronic device. The electronic device may measure a voltage of power that is input to a power supply terminal of the interface connector that includes the power supply terminal and is configured to connect with an external device. The electronic device may identify a type of the external device connected to the interface connector based on the voltage of the input power. In addition, other embodiments are also possible.

Method and apparatus for identifying external device

Provided is a method for controlling charging in a mobile terminal. The method includes, applying a voltage to a charger upon detecting a connection to the charger via a cable; transmitting a signal for requesting charging to the charger, and switching a charging mode; and charging a power that is received from the charger according to the switched charging mode.

Mobile terminal and method for controlling charging and charger therefor

A charging cradle for mounting a portable terminal or a battery pack for the portable terminal, a multi-plug adapted to be mounted by being inserted into the charging cradle, hook holes formed in the charging cradle, and hooks adapted to be engaged with the hook holes, wherein the direction for inserting the multi-plug into the charging cradle and the direction for connecting the multi-plug to an external receptacle are perpendicular to each other, is provided, so that charging cradles adapted to be commonly used worldwide, and by localizing multi-plugs by countries or cities, i.e., by providing each country or city with multi-plugs adapted to be suitably used in such a country or a city, enable a user to use his or her charging device by only buying a multi-plug available in a country or a city where the user stays if it is desired.

Charging device for portable terminal

An electronic device including a housing, a main circuit substrate disposed in one side of the housing; a connector unit which is disposed in an other side of the housing and is electrically connected to the main circuit substrate, and a discharging sheet disposed in the one side of the housing and is conductively connected to the connector unit to discharge static electricity generated in the connector unit is provided.
