Abstract
One embodiment provides a circuit arrangement integrated in a semiconductor body. At least one power semiconductor component integrated in the semiconductor body and having a control connection and a load connection is provided. A resistance component is thermally coupled to the power semiconductor component and likewise integrated into the semiconductor body and arranged between the control connection and the load connection of the power semiconductor component. The resistance component has a temperature-dependent resistance characteristic curve. A driving and evaluation unit is designed to evaluate the current through the resistance component or the voltage drop across the resistance component and provides a temperature signal dependent thereon.
