My customer found DRV3245 sometime will trig the STP_FAULT and DEADT_FAULT in their system, when the MCU's PWM with 1.5us deadtime(Setting by MCU). After checking the register setting, they found the 0x07 set as followed:
The TBLANK set as 0us, the Dead_time set as 150ns.
1. If the TBLANK=0s, is it more easily to trigger the STP_FAULT?
2. Is the DEAD_FAULT triggered by the STP_FAULT in customer's system? For this setting, the DEAD_TIME set by DRV3245 is 150ns, but the MCU's output with 1.5us deadtime, which should not trigger the DRV3245's DEAD_FAULT.
