PN5180 low power card detection current consumption

Hi,

I'm investigating the RFID front end PN5180 and wonder if there exists app.note´s, calculations etc on the average current/power consumption for the Low power card detect (LPCD) mode, since I want to create an RFID reader that can operate on a small battery for a long time and the actual amount of real RFID tag accesses will be very low compared to the total time the reader needs to be in "read" mode.

 

I have looked in the datasheet for PN5180 but there is no info on the "average/standard" ON and OFF times, and also the duty cycle and frequency for the ON sequence needed for the RF transmitter field to be able to detect a RFID tag with a certain responce time.

 

Anyone out there that can assist ?
