Hey, Can anyone help me with the minimum power level required for PN512 to detect a passive tag. 

and the maximum output power from PN512 to reader antenna. 

The sensitivity of the reader using PN512.

DearSam Malik,

If you mean the power level required on VANT, basically there is no minimum. Although the level of field power will definitely depends of the power level delivered (linked to input voltage and tuning resistance value). The only way to define the minimum value, in order to reduce the power consumption, still allowing proper detection of tags is to make trials. Pay attention that it will be highly linked to the tags characteristics, indeed tags do not all requires the same power level to operate.
