DRV8251A: DRV8251A - Max Current Limit threshold

Tool/software:

HI there,

Couple questions on setting the current limit threshold

1) What is the current consumption on VREF ?  Is a voltage divider allowed on this pin ?

2)  If I look at the Fig 7-9 in the datasheet, it mentions Viprop <3V but Current up to >3A. I believe Viprop can be 5V from the ABS MAX spec or is this output clamped?

Trying to figure out how to set the Trip/Limit threshold above 2A. Right now if I look at using 3.6V for Vref and 3.6V for Viprop (Riprop = 1.2K), Itrip is around 1.9A. Just wanted to clarify. 

Thanks for the help!
