Abstract
An UVLO circuit according to an aspect of the present invention includes: a power-on reset (POR) circuit generating an output based on a first current that flows according to an increase of a power supply voltage and not operating in a normal state of the power supply voltage; and a logic operation unit generating a reset signal according to an output of the POR circuit and an output based on a result of comparison between a sense voltage that corresponds to the power supply voltage and a predetermined reference voltage.
