Abstract
A charge-pump control circuit includes an oscillator which supplies a clock for driving a charge pump driver to supply a first gate voltage to a discharging transistor in order to control discharge from a battery, and driving a charge pump driver to supply a second gate voltage to a charging transistor in order to control charge to the battery, respectively; and a drive control circuit which sets a control target voltage as one of the first gate voltage and the second gate voltage having a lower voltage in order to control generation of the clock by the oscillator according to the control target voltage.
