DRV8301 Default value of internal control register.

Other Parts Discussed in Thread: DRV8301

My customer is using DRV8301 by not using SPI.
DRV8301 is operated with default control register value.
Default register value is shown as bold number in Table7,8 of datasheet.

I think that control register value is changed to default value by reset of DRV8301.
Is my idea correct?

Thanks

Hi Shimizu,
You are correct. An EN_GATE reset will revert the SPI registers to their defaults.

Hi Nick

Thank you for your support.
I would like to confirm just in case; Does that a power supply falls also cause?

Thanks
Shimizu

The registers will also revert to default values if PVDD1 drops below the UVLO threshold. We are working to clarrify this in the datasheet.
