An H-bridge pre-driver is configured as two blocks so as to suit the width of an H-bridge driver Tr. The two blocks are line-symmetrically placed with a bias circuit interposed therebetween. One of the pre-driver blocks is laid out as a rectangle that is long in one direction and is short in a direction perpendicular to that direction. With this configuration, the pre-driver layout area can be reduced, and the cost of IC can be reduced. Furthermore, the symmetric placement enables matching of the impedance of interconnect from the pre-driver to the driver and stabilization of properties to be achieved.
