摘要:
An integrated circuit arrangement includes a semiconductor body having a substrate and at least one substrate terminal. At least one semiconductor component is integrated in the semiconductor body and is connected between a first supply terminal and a second supply terminal. The first supply potential is higher than the second supply potential during normal operation of the semiconductor component and the first supply potential is lower than the second supply potential during reverse voltage operation of the semiconductor component. A switch is adapted to couple at least one of the substrate terminals to the first supply terminal during reverse voltage operation and to the second supply terminal during normal operation.
