Abstract
A voltage detecting circuit that has a stable output even when a battery voltage is low includes first and second terminals connected across poles of a battery, a reference voltage generating circuit, and a comparator for comparing values of the reference voltage and voltage across the terminals. A first output circuit is connected between the first and second terminals to output a first output signal on the basis of the comparison result, a second output circuit outputs a second output signal that changes in value based on a voltage of the battery and on the basis of signals at the first and second terminals, and an output terminal outputs the first and second output signals.
