7.3.9 Thermal Shutdown

The TPS51396A monitors the internal die temperature. If the temperature exceeds the threshold value (typically 150°C), the device is shut off and the output will be discharged. This is a non-latched protection, the device restarts switching when the temperature goes below the thermal shutdown threshold.
