SNVSBZ6 May 2021 TPS92380 , TPS92381
PRODUCTION DATA
If the die temperature of TPS9238x reaches the thermal shutdown threshold TTSD, which is 165°C typical, the boost, power-line FET and LED outputs are turned off to protect the device from damage. The FAULT pin will be pulled low. The TPS9238x will exit FAULT RECOVERY mode after 100 ms and try the start-up sequence again. Only if the die temperature drops lower than TTSD - TTSD_HYS, which is 145°C typical, the device could start-up normally. TSD fault detection is available in SOFT START, BOOST START and NORMAL state.
