Abstract: A circuit device includes a pulse signal output circuit and a driving circuit. The pulse signal output circuit, when a detection voltage has decreased below a reference voltage, changes a pulse signal to an active level at which a switching element is turned on. The pulse signal output circuit, after the detection voltage has decreased below the reference voltage, performs monitoring as to whether or not the detection voltage has exceeded the reference voltage, and upon detecting that the detection voltage has exceeded the reference voltage, changes the pulse signal to an inactive level at which the switching element is turned off. The driving circuit outputs a driving signal based on the pulse signal to the switching element.
