ABSTRACT:
A motor driving device for rotating a motor in forward and reverse directions which includes a switching circuit arranged in an H-bridge connection with both terminals of the motor, a controlling circuit, and an interception device provided on the respective terminal sides of the motor. The switching circuit includes two sets of switching transistors. The interception device protects the switching circuit by preventing both transistor sets from entering the ON-state at the same time, and thereby prevent the switching means from breaking down.
