    • An apparatus and method for determining a status of a power unit in a portable terminal are provided. The apparatus includes a power unit for supplying power to a internal circuit, a resistor located between the power unit and the internal circuit, and a voltage determination unit for determining an amount of a current consumption by the internal circuit by considering a difference between a first voltage between the power unit and the resistor and a second voltage between the resistor and the internal circuit, and for determining status information of the power unit by compensating for a voltage drop of the first voltage in accordance with the amount of the current consumption.
    • 提供了一种用于确定便携式终端中的功率单元的状态的装置和方法。 该装置包括用于向内部电路供电的电力单元,位于电力单元和内部电路之间的电阻器,以及电压确定单元,用于通过考虑内部电路的第一和第二电压之间的差异来确定内部电路的电流消耗量 功率单元和电阻器之间的电压以及电阻器和内部电路之间的第二电压,并且通过根据电流消耗量补偿第一电压的电压降来确定功率单元的状态信息。
