DRV8412: Fault pin is not working

$

Part Number:DRV8412

Hello,

During an initial test of getting the device to a fault state, I noticed that the outputs do shut off but the fault pin does not go low.

After looking into this with an oscilloscope I saw that during the time it goes on the fault line and AGND seem to increase by 1.6V!!!

Do you think I have a grounding issue? The mode pins also connect to AGND, so what behavior can happen if all mode pins go to 1.6V

I am using mode 1 and I have done this before with the DRV8412DDWEVM and the fault pin works there with the same test.
