Abstract
A motor driving semiconductor device has: six switching elements for driving a three-phase motor; three output terminals for applying output voltages to three terminals of coils of the three-phase motor; drive circuits for driving the six switching elements; and six control signal input terminals for receiving six control signals for on/off control of the six switching elements, wherein the motor driving semiconductor device is formed by sealing at least one semiconductor chip in one package with resin, and further includes a dead time generation function of generating a dead time relative to the six control signals.
