Abstract
An integrated circuit includes an asymmetry upper threshold circuit outputting an upper-branch enabling signal, an asymmetry lower threshold circuit outputting a lower-branch enabling signal, and a control circuit which changes an output voltage when the logic levels of the upper-branch enabling signal and the lower-branch enabling signal are changed consecutively. The upper-branch enabling signal is set to a first upper-branch logic level when an input voltage received by the integrated circuit rises across a main upper threshold, and to a second upper-branch logic level when the input voltage falls across a supplementary upper threshold which is higher than the main upper threshold. The lower-branch enabling signal is set to a first lower-branch logic level when the input voltage falls across a main lower threshold, and to a second lower-branch logic level when the input voltage rises across a supplementary lower threshold which is lower than the main lower threshold.
