Abstract
The present invention relates to a switch driving circuit and a driving method thereof. The switch driving circuit according to the present invention is supplied with a first voltage and a second voltage, is driven by a voltage difference between the first and second voltages, controls a switching operation of a power switch according to a switch driving control signal, generates a sense voltage corresponding to the second voltage, compares a predetermined reference voltage with the sense voltage, and stops the switching operation of the power switch according to the comparison result.
