Abstract: A small and low-cost load driving circuit device that reduces common mode noise without using a transformer, has a first switching arrangement provided between a high potential source and a terminal of an electrical load; a second switching arrangement provided between ground and the other terminal of the electrical load; a control arrangement that controls the first and second switching arrangements so as to simultaneously disconnect each other with the same frequency and the same duty ratio; and a synchronization arrangement that synchronizes the disconnect timing of the first switching arrangement and the disconnect timing of the second switching arrangement.
