DRV2605: Why was the recommended value of C(vdd) increased from 0.1uF to 1uF?

Andrew Nicol

Part Number: DRV2605

Why was the recommended value of C(vdd) increased from 0.1uF to 1uF? in Rev E of the datasheet. Should legacy designs be updated?

Hi Luis,

Thank you for the quick response.

I noticed the change and wanted to double check that this was not associated with a reported issue.

There are still a few places in the latest datasheet where the values are interchanged.

Thanks,

Andy.
