Abstract
An electronic circuit arrangement for monitoring temperatures includes an electronic temperature-determining circuit with a temperature sensor for measuring an ambient temperature in the surroundings of the temperature sensor, configured to generate a comparator input signal depending on the temperature measured by the temperature sensor, an electronic reference circuit including a secondary temperature sensor for measuring an ambient temperature of the electronic circuit arrangement which is configured to generate a secondary comparator input signal that is dependent on the temperature measured by the secondary temperature sensor, an electronic comparator circuit which compares the primary and the secondary comparator input signal and generates a comparator output signal dependent on the two input signals. The temperature-determining circuit, the reference circuit and the comparator circuit are configured such that the comparator circuit generates a trigger signal as the comparator output signal if the temperature measured by the temperature sensor exceeds a temperature reference value.
