Abstract

An integrated circuit having a first connection, a second connection, a substrate, and a control connection, in provided. The control connection controls a conductivity of the integrated circuit between the first connection and the second connection. The integrated circuit further includes a first transistor and n additional transistors with conductive paths connected between the first connection and the second connection, n diodes, each of the n diodes being connected between a control connection of the n transistors and a driver supply voltage that corresponds to the voltage at the first connection combined with an additive offset, and wherein the control connection of the integrated circuit connects either the driver supply voltage or the voltage at the first connection to a control connection of the first transistor, and a voltage divider that is connected between the first connection and the second connection in parallel to the conductive paths and that connects the control connections of the transistors to one another and to both the first connection and the second connection. The control connections of each set of two transistors are connected to one another by a subsection …
