Abstract

A power voltage detecting circuit includes a voltage regulating circuit, a comparative circuit and a display circuit. The voltage regulating circuit provides a stable reference voltage to the comparative circuit. The comparative circuit detects a power voltage. The display circuit shows states of the power voltage. The power voltage detecting circuit further includes a time circuit. The comparative circuit is electrically connected to the display circuit via the time circuit. The time circuit keeps the display circuit to display exceptional states of the power voltage.
