摘要： A signal transfer circuit in a pre-drive circuit converts the reference potential of a control signal, supplied from a drive control circuit, to the reference potential of an output element. The control signal is then amplified in a signal amplifier circuit and thereafter supplied to the output element. This makes it possible to isolate the reference potential and transfer the control signal to the output element even when the reference potentials of the drive control circuit and the control signal are different from that of the output element. The drive control circuit can also be prevented from being affected by variations in potential of the output element or the like.
