PRODUCTION DATA
If the die temperature exceeds the thermal warning limit (TOTW), nFAULT is pulled low and the OT and OTW bits in the gate driver status register are set to 1b. The reporting of OTW (on nFAULT and status bits) can be enabled by setting OTW_REP to 1b. The device performs no additional action and continues to function. In this case, the nFAULT pin is released when the die temperature decreases below the hysteresis point of the thermal warning limit (TOTW - TOTW_HYS). The OTW bit remains set until cleared through the CLR_FLT bit and the die temperature is lower than thermal warning limit. (TOTW - TOTW_HYS).
