| 20090113222 | TERMINAL HAVING REAL TIME CLOCK (RTC) OPERATOR AND METHOD OF RTC OPERATION USING THE SAME - A method of operating a Real Time Clock (RTC) in a terminal is provided. The method includes detecting a clock signal transmitted to an RTC block when the main power supply is switched off, and supplying a power to the RTC block for its operation by charging and discharging the power periodically supplied from the backup battery according to the detected clock signal. A DC/DC converter connected to a backup battery is periodically switched on and off, and a capacitor is charged and discharged using the power of the backup battery, thereby avoiding supplying power from a backup battery continuously to an RTC block. Therefore, power consumption is reduced and a duration of time for maintaining RTC data is extended. | 04-30-2009 |
| 20110140661 | METHOD AND APPARATUS FOR CONTROLLING BATTERY CHARGING OF PORTABLE DEVICE - A device and method for controlling the charging of a portable terminal is provided. The device includes an external power supply interface unit for supplying an external power, a battery interface unit to which a main battery and a sub battery are connected, and a charging controller for controlling a charge of the main battery or a simultaneous charge of the main battery and the sub battery. | 06-16-2011 |
