7.3.7.3.3 Thermal Shutdown

The LP87524B/J/P-Q1 has an overtemperature protection function that operates to protect the device from short-term misuse and overload conditions. When the junction temperature exceeds around 150°C, the regulators are disabled, the TDIE_SD bit (in INT_TOP1 register) is set to 1, the nINT signal is pulled low, and the device enters STANDBY. nINT is cleared by writing 1 to the TDIE_SD bit. If the temperature is above thermal shutdown level the interrupt is not cleared. The host can read the status of the thermal shutdown from the TDIE_SD_STAT bit (in TOP_STAT register). Regulators cannot be enabled as long as the junction temperature is above thermal shutdown level or the thermal shutdown interrupt is pending.
