PROBLEM TO BE SOLVED: To selectively drive an H-bridge circuit along with a peripheral circuit to which the H-bridge circuit is connected without using a control unit such as a CPU.SOLUTION: A state acquisition unit 112 and a data control unit 121 discriminate peripheral circuits connected to H-bridge circuits H11, H12, and H13 according to whether a voltage supplied to the peripheral circuit 141a is fed back to a holding unit 113. |
