Abstract
The present invention inhibits the voltage jump of a source voltage or an output voltage by an approach which is different from a conventional one. A logic circuit allows an H bridge circuit to be shifted among a plurality of states in a specific sequence. A compulsory regenerating circuit is configured to be switched between an enabled state and a disabled state; while being in the enabled state, the current that flows in from a ground line via the H bridge circuit and a motor coil to a power line back-flows to the ground line.
