Abstract:
In a low voltage detection circuit having improved detection performance, the low voltage detection circuit includes: a comparison voltage generator for generating a first comparison voltage and a second comparison voltage having a level higher than that of the first comparison voltage by dividing a power voltage; a first comparator for outputting a low voltage detection enable signal by comparing the first comparison voltage with a reference voltage; a second comparator for outputting a detection signal by comparing the second comparison voltage with the reference voltage while the low voltage detection enable signal is being input; a detection signal maintainer for providing a low voltage detection signal to an output terminal according to the detection signal; and an output signal discharger for discharging the low voltage detection signal according to the low voltage detection enable signal.
