Abstract
A reset signal generator may include a voltage divider dividing a voltage level of a driving voltage, a reference voltage generator generating a reference voltage by performing a switching operation on the driving voltage depending on a voltage level of the divided driving voltage from the voltage divider, and a comparator comparing the voltage level of the divided driving voltage and the reference voltage to output a reset signal depending on the comparison result. The integrated circuit includes the reset signal generator and a controller resetting a control operation depending on the reset signal.
