发明名称 Semiconductor device for motor driving and motor having the same, motor driving apparatus and air conditioner
摘要 A motor driving semiconductor device (10) has: six switching elements (T1-T6) for driving a three-phase motor; three output terminals (P9-P11) for applying output voltages to three terminals of coils of the three-phase motor; drive circuits (KT, KB) for driving the six switching elements; and six control signal input terminals (P1-P6) 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.
