Abstract:
A drive circuit is provided for driving a plurality of object switches mutually connected in parallel. The drive circuit includes: an off holding switch provided for each of the object switches, short-circuiting between a control terminal of each object switch and a reference potential unit to which discharge from the control terminal is discharged; and off control units each provided for the off holding switch. The off holding switch is driven by an own control unit and other control units. The own control unit is provided as an off control unit corresponding to own off holding switch, among the off control units. Other control units are at least one of the off control units other than the own control unit.
