DRV8332: GVDD to Gnd short

Part Number: DRV8332

We are using a DRV8332 for sinusoidal control of a BLDC motor.

The chip operates correctly for a while and then randomly fails; I measure a short between the GVDD pins and Gnd. I have replaced the chip twice so far, so I would like some assistance in determining what might be causing this problem.

PVDD is set to 37V

During typical operation the BLDC motor is drawing between 1-5 Amps of current.

Best Regards,
