Abstract: An H bridge circuit that is connected to nodes N1 and N2 for a power source and nodes N3 and N4 for a motor includes: a PchMOS transistor that is disposed in an N-type first region and is connected between N1 and N3; an NchMOS transistor that is disposed in an N-type second region and is connected between N2 and N3; a PchMOS transistor that is disposed in an N-type third region and is connected between N1 and N4; and an NchMOS transistor that is disposed in an N-type fourth region and is connected between N2 and N4, in a P-type semiconductor substrate. The distance between the first region and third region is smaller than the distance between the first region and second region, smaller than the distance between the third region and fourth region, and smaller than the distance between the second region and fourth region.

Abstract: A circuit device includes: a comparator that outputs an output signal that is activated when a potential of an input terminal is lower than a determination level; a switch circuit that is electrically connected between an output node connected to a switching element that enters a conduction state or a non-conduction state according to a drive signal and the input terminal of the comparator, and is in a non-conduction state when the switching element is in a conduction state; and a control circuit that controls a level of the drive signal such that the switching element will not enter a conduction state again based on a period during which or the number of times the output signal of the comparator is activated after the switching element has transitioned from a conduction state to a non-conduction state.
