Hello,
I've changed the impedance matching network on the NFC06A1 such that the system is resonant at 13.56MHz with an impedance of 2.6 ohms. The reader is in 5V mode with the regulator display register measuring 4.3V at VDD_RF. I have set the output resistance to 3.4 ohms.
I expect that it would output 1.6 Arms (4.3 V / 2.6 ohm) or possibly 0.72 Arms (4.3 V / (2.6+3.4) ohms) with the VDD_RF regulator limiting the current to 350Arms. However, the i_lim flag remains zero.
Is there a trouble shooting procedure I should follow for determining why the device will not output more than 350Arms?
Thank you!
Best,
Oliver
