7.2.2 TMP392 With 10°C Hysteresis

Figure 7-3 shows an example circuit for dual overtemperature protection using the TMP392. In this example, the trip points are set at +60°C and +90°C with 10°C hysteresis. This circuit is useful in cases where a lower overtemperature detection can be used to warn the application of rising system temperature and take software corrective actions such as lowering the performance, while the higher overtemperature detection can be used to start a fan to cool the system to a lower temperature.
