SLVSEE8B November 2019 – May 2021 DRV8899-Q1
If the die temperature falls below the trip point of the undertemperature warning (TUTW), the UTW and TF bits are set in the SPI register. The device performs no additional action and continues to function. When the die temperature exceeds the hysteresis point (THYS_UTW) of the undertemperature warning, the UTW and TF bits clear automatically. The UTW bit can also be configured to report on the nFAULT pin, and set the FAULT bit in the device, by setting the TW_REP bit to 1b through the SPI registers. The charge pump remains active during this condition.
