Controlling BLDC with IR 2130 - stuck at fault, unable to reset
the /FAULT output is an open-drain output. You need an external pull-up resistor to your VCCIO logic supply voltage (3.3V or 5V).

The open-drain output has a low-on resistance in the 55-75 Ohm range. Any pull-up value comprised between 1k and 10k should do the job.
