Abstract
Under-voltage, over-voltage, and temperature detectors disposed in a switching circuit are turned on periodically and in response to an oscillating signal having a low duty cycle. Accordingly, because the voltage and temperature detectors remain off for long durations, their operating currents, and thus the operating current of the switching circuit is substantially reduced. The switching circuit has a current limiting function which is disabled when the switch current is below a threshold value, thereby further decreasing the current consumption of the switching circuit at low switch current levels.
