Hi Richard,
Apologize for the delay.
Potentially the customer could use the high-side MOSFETs with the load referenced to ground instead of the low-side MOSFETs. This would allow correct power up through EN_GATE.
The other potential option would be to add an external high-side Load-Switch that would turn on after EN_GATE Is brought logic high on the DRV8301.
Is their a reason the customer needs to use the DRV8301? Our new family of devices called the DRV832x parts may be a better fit for this solution.
