May I set CLRC663 RF alaways on?

[gogopass]

Hello Sir:

I have a card reader project with CLRC663.

Because of special card it need more power,

I need to set the RF field always on else RF field  reset.

Does CLRC663 have any note to attention?

Or it's dangerous in this condition?

Thank your any reply .

Hi Carlos,

It is ok to switch on RF filed out of reset, just make sure the max ITVDD within the spec. For CLRC66301 and CLRC66302 , it is 250mA and for CLRC66303 it is 500mA.

Have a great day,
Kan
