More Information
Summary:A circuit arrangement disposed on a substrate, in particular integrated onto a semiconductor chip, has at least two power components which are arranged adjacent one another and which are assigned at least one temperature sensor. For a number n of power components, at least n+1 temperature sensor elements are arranged on the substrate such that each of at least n−1 temperature sensor elements has an approximately equal distance to two power components, or each of the n power components has an approximately equal distance to two temperature sensor elements. An analyzing circuit is provided in order to detect an excess temperature. The analyzing circuit analyzes at least the two temperature sensor elements lying closest to a power component with respect to an excess temperature.
