Abstract:
An electronic device is provided. The electronic device includes a housing, a battery included within the housing, a connector electrically connected to an external power supply device including an integrated circuit (IC) and exposed to a part of the housing, and a power management unit included within the housing and electrically connected to the connector, wherein the power management unit is configured to communicate with the IC of the external power supply device, and wherein the connector is configured to receive a first current of a first current value during at least a part of the communication and to receive a second current of a second current value greater than the first current value during at least a part in which the communication is not performed.
Abstract:
An electronic device comprising: an interface arranged to connect to an external power supply device and supply power to a battery; a sensor unit arranged to measure a temperature of the electronic device; and a power management unit configured to charge the battery based on the temperature.
Abstract:
An apparatus for supplying power in a mobile terminal is provided. The apparatus includes a battery, a power management integration circuit including a buck-boost converter for converting a battery voltage to output a specific voltage, and a plurality of regulators for regulating the specific voltage output from the buck-boost converter to voltages of respective corresponding constituent elements and for outputting the regulated voltages, the buck-boost converter operating in a buck mode when the battery voltage is greater than the specific voltage, and the buck-boost converter operating in a boost mode when the battery voltage is less than the specific voltage, such that the constituent elements include a controller for controlling an operation of the mobile terminal, a touch panel for generating an input and for providing the generated input signal to the controller, and a display unit for displaying an operation of the mobile terminal under control of the controller.
Abstract:
A battery charging control system of a terminal is provided. The system includes a terminal in which a battery is mounted and a charger connected to the terminal to provide a charging current for charging the battery. The charger charges the battery with a maximum margin current value that is greater than a rated current value of the charger.
