Abstract
A semiconductor device includes a semiconductor chip including an active area. A temperature sensor arrangement provides a measurement signal dependent on the temperature in or close to the active area. An evaluation circuit is configured to compare the measurement signal with a first threshold and to signal an over-temperature when the measurement signal exceeds the first threshold. The evaluation circuit is also configured to count the number of exceedances of the first threshold and to signal when a maximum number of exceedances is reached.
