Circuit Arrangement Which is Arranged on a Substrate and Which Comprises a Temperature Monitoring System, and Method for Detecting an Excess Temperature

A circuit arrangement on a substrate, comprising:

• a number n power components with at least two power components disposed adjacent one another on the substrate;
• at least n+1 temperature sensor elements assigned to said power components;
• said temperature sensor elements being arranged on said substrate such that:
• each of at least n−1 temperature sensor elements are disposed at a substantially identical spacing from two respective said power components;
• or
• each of said n power components is disposed at a substantially identical spacing from two respective said temperature sensor elements;
• and
• an evaluating unit connected to said temperature sensor elements and configured for identifying an over-temperature, said evaluating unit evaluating at least two said temperature sensor elements lying closest to a power component for identifying an over-temperature of the respective said power component.
