NX5P3090 FAULT pin voltage with Vin=0V

Hello. I am using the NX5P3090 USB power switch and would like to pull the open-drain FAULT output to a 1.8V supply that can be present even if there is no input to the switch (Vin=0V). Will the presence of 1.8V at the FAULT pin (through a 47kohm pullup) when Vin=0V cause any undesirable behavior in the switch? I see that there is a 6V absolute limit on this pin but it isn't clear to me if this applies when Vin=0V. Thank you.  -Jason

Hi 

1.8v pull up for this FAULT pin will be no problem without VIN.
