SNVSBK2 September 2019 LP8733
The LP8733xx device includes a protection feature against overtemperature by setting an interrupt for the host processor. The threshold level of the thermal warning is selected with the TDIE_WARN_LEVEL bit in the CONFIG register.
If the LP8733xx device temperature increases above the thermal warning level, then the device sets the TDIE_WARN_INT bit in the INT_TOP_1 register and pulls the nINT pin low. The status of the thermal warning can be read from the TDIE_WARN_STAT bit in the TOP_STAT register, and the interrupt is cleared by writing 1 to the TDIE_WARN_INT bit. The thermal warning interrupt can be masked by setting the TDIE_WARN_MASK bit in the TOP_MASK_1 register to 1.
