Hello PriyanshK,

Yes. It can be pulled to 3.3V when Vdd=5V. 

STATUS Pin potential should be >2.6V in order to be detected as high by the internal logic when VDD=5V. 

But  if this STATUS pin input is given to an external microcontroller, please also check if the microcontroller is compatible with this potential.
