ABSTRACT:
An integrated circuit for driving a semiconductor device, which is adaptable for demands, such as a higher output (larger current), a higher voltage, and a smaller loss, and has a small size, is produced at a low cost, and has high reliability. A power converter including such an integrated circuit is also provided. Circuit elements constituting a drive section of an upper arm drive circuit212, a level shift circuit20including a current sensing circuit210, a drive section of a lower arm drive circuit222, and a drive signal processing circuit224are integrated and built in one high withstand voltage IC chip200. Circuit elements constituting a final output stage buffer section213of the upper arm drive circuit212are built in a vertical p-channel MOS-FET chip213pand a vertical n-channel MOS-FET chip213n. Circuit elements constituting a final output stage buffer section223of the lower arm drive circuit222are built in a vertical p-channel MOS-FET chip223pand a vertical n-channel MOS-FET chip223n. Thus, a driver IC2is fabricated.
