2.5 Window Monitoring Threshold

In combination, TI has a selection of devices that can collect both over- and undertemperature detection with two temperature limits. Each limit includes an associated hysteresis value to prevent false triggering caused by noise and minor temperature fluctuations near the threshold. Two limits are defined as high and low temperature thresholds. The alert does not recover until the temperature has reached the hysteresis set value.
