The TPS929240-Q1 has overtemperature protection at T(TSD1), typical 175°C in FAIL-SAFE state.
When device junction temperature T(J) further rises above overtemperature protection threshold, the device turns off all output drivers, pulls the ERR pin low with constant current sink to report fault, and sets the flag registers including FLAG_TSD and FLAG_ERR to 1.
The fault is latched in flag registers. When the junction temperature falls below T(TSD1) – T(TSD1_HYS), the device resumes all outputs and releases ERR pin pulldown. The master controller must write 1 to CLRFAULT to clear FLAG_TSD and FLAG_ERR. The CLRFAULT bit automatically returns to 0.
