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 circuit, a level shift circuitincluding a current sensing circuit, a drive section of a lower arm drive circuit, and a drive signal processing circuitare integrated and built in one high withstand voltage IC chip. Circuit elements constituting a final output stage buffer sectionof the upper arm drive circuitare built in a vertical p-channel MOS-FET chipand a vertical n-channel MOS-FET chip. Circuit elements constituting a final output stage buffer sectionof the lower arm drive circuitare built in a vertical p-channel MOS-FET chipand a vertical n-channel MOS-FET chip. Thus, a driver ICis fabricated.
