DRV8885 - VRREF exceeding 1.28V when controlling IFS using a DAC

$

Hi Team,

When controlling chopping current with the DAC (0V to 3.3V), there could be a possibility to apply voltage above VRREF (1.28V). I understand that the device would not properly operate, but, what would happen to the device and the operation ?

Customer is worrying about operation safety. I believe the device would not have a critical damage.

Best Regards,

Kawai
