ZHCSJW0D June 2019 – March 2020 TPS62840
The junction temperature (TJ) of the device is monitored by an internal temperature sensor. The device enters thermal shutdown when the junction temperature exceeds the thermal shutdown threshold (TSD) of 160°C (typ.). Both the high-side and low-side MOSFETs are turned off. The device resumes its operation when the junction temperature falls below typically 155°C again and begins with a soft-start cycle without reading RSET again. In Power-Save Mode, the thermal shutdown feature is disabled.
