6.3.4.2 Absolute Overtemperature (TSD)

Aside from the dynamic temperature protection and monitoring, the FET also has a absolute temperature sensor. Triggering this sensor results in a channel shut off, followed by the STATUS pulled low. The channel retries once the temperature falls below TTSD_hys.

Note: Only Absolute overtemperature events can cause the STATUS to go low. Recovery of the STATUS pin however can happen only if the Dynamic Overtemperature sensor has fallen below ΔTDYN - ΔTDYN_hys and the FET temperature sensor falls below TTSD_reset
