Abstract: An integrated temperature sensor delivers threshold detection signals when temperature thresholds have been exceeded. The temperature sensor includes a circuit for detecting a first temperature threshold having a first detection threshold, and for detecting a second temperature threshold having a second detection threshold. The circuit also detects a third temperature threshold between the first and second temperature thresholds, and detects a fourth temperature threshold between the first and second temperature thresholds. The third temperature threshold has a third detection threshold linked with the first detection threshold so that a deviation of the first detection threshold causes a corresponding deviation of the third detection threshold. Similarly, the fourth temperature has a fourth detection threshold linked with the second detection threshold so that a deviation of the second detection threshold causes a corresponding deviation of the fourth detection threshold. The third and fourth temperature thresholds define a temperature window to test the temperature sensor for detecting a deviation of the first and second detection thresholds.
