SLVSEE8B November 2019 – May 2021 DRV8899-Q1
If the die temperature exceeds the trip point of the overtemperature warning (TOTW), the OTW and TF bits are set in the SPI register. The device performs no additional action and continues to function. When the die temperature falls below the hysteresis point (THYS_OTW) of the overtemperature warning, the OTW and TF bits clear automatically. The OTW 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.
