hi, we are uing DRV8316T hardware mode to driver motor, we have not connet motor phase wires.
On oscilloscope, we have see nFault signal erery 5ms and last 20us,Do you know the possible reasion?thanks a lot!

Hey,
Thank you for the question. I will aim to provide an update next week.

Hey,
Sorry for the delay.
Please find schematic review attached here.E2E schematic 8316- TI Reviewed.pdf
I recommend consulting the folwoing two FAQs to help diagnose which fault is occuring.
Also can you please share your duty cycle and PWM frequency? Along with a waveform of nfault, phase current and VM voltage?
It seems like it is an overcurrent issue as 5ms is the retry time for this device.
Best,
Akshay
