DRV3255-Q1: Driver operation on power-up without SPI access

Part Number: DRV3255-Q1

Hello,

our motor drive application might have a mode where we want to power-up the driver and have the PWM inputs drive the gate drive outputs without any configuration over SPI.
We have found with some other vendors drivers that they all need at least one SPI access to enable the gate drive outputs even though the power-up default register settings would work.

Does the DRV3255-Q1 need any SPI accesses for it to enable the gate drive output control by the PWM inputs?

Thanks,
Ian

    Hi Ian,

    Unfortunately I am unable to discuss these specifics publicly without an NDA, but depending on the scenario the DRV3255 may have some features that may help. I wish I could discuss more but unfortunately due to NDA I can't.

    Regards,
