Abstract
A circuit device includes a first switching circuit that has one end connected to an output node, and turns on and off according to a drive signal, a second switching circuit that is connected in series with an impedance element between another end of the first switching circuit and a node having a predetermined potential, and turns off and on complementarily with the first switching circuit, a comparator circuit that outputs an output signal indicating whether or not a potential of the other end of the first switching circuit is higher than a determination level, and a control circuit that controls a level of the drive signal based on the output signal of the comparator such that the switching element enters a non-conduction state.
