DRV8311: The output voltage of nFAULT pin issue

Hi,

We uset the DRV8311 in our project, and now, we measure the output voltage of nFAULT pin is 1.0V when the power on, and we change the RnFAULT from 10Kohm to 5.1Kohn(Same as the datasheet), the output voltage is also 1V, pleaes kindly review below schematic and provide your comment is there any error, thanks.
