Hi Champs,
I need to clarify for a customer if there is a specified supply voltage rise-time for the DRV8821.
They have problems on the field and found the DRV8821 in a lock up state. After they increased the risetime of the power supply the issue did not happen again.
To get sure that the problem is resolved with this change they would need to know if there is a minimum rise-time specified which is not mentioned in the datasheet!? Did you hear of this issue before?
