Abstract
The electronic apparatus including a DC motor that is driven based on a current supplied from a power source, and including: a detection circuit that detects an instantaneous interruption of the power source; an H bridge circuit having an upper arm circuit having two switching elements connected in parallel to the power source and a lower arm circuit having two switching elements connected in parallel to a ground, the upper arm circuit and the lower arm circuit being connected in series, and controlling a current to be supplied to the DC motor; and a switching control circuit that controls the switching element, and in a case where an instantaneous interruption of the power source is detected by the detection circuit, the switching control circuit sets the switching elements of the upper arm circuit to off and sets the switching elements of the lower arm circuit to on.
