<p><P>PROBLEM TO BE SOLVED: To reliably suppress a decrease in high potential-side power supply voltage due to an undershoot of a negative voltage generated at a high potential-side reference potential (virtual ground potential VS) in a power device driving circuit. <P>SOLUTION: In a high voltage control circuit (HVIC), a high-breakdown-voltage diode D3 is provided between a common ground node (COM) and a virtual ground node (VS) by using a common substrate region. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
