摘要： A fuel gauge system for measuring the amount of current in a battery is provided. The fuel gauge system includes a first resistive element connected in series to the battery, a second resistive element connected in series to the first resistive element, a first switch connected in parallel to the second resistive element to control a current flowing in the second resistive element, a second switch connected in series to the second resistive element to control the current flowing in the second resistive element, a controller configured to output a first switching signal to the first switch and output a second switching signal to the second switch, and a fuel gauge circuit configured to measure a battery current flowing in the first resistive element and the second resistive element.

摘要： A DC-DC converter is provided. The DC-DC converter includes at least one converter circuit configured to include an inductor and to supply a current to a load through the inductor; and a controller configured to sense the current to generate a sensed signal, to sample and hold the sensed signal at a predetermined sampling time to detect an average current of the inductor, and to control an operation of the at least one converter circuit according to the average current. The sampling time is set to a time in a period while the inductor current is less than a peak and greater than a valley.
