AS3956 − Electrical Characteristics

Note(s):

1. ILC is the current flowing through LC1 and LC2 pins. Exposure to very strong RF fields which produce currents as high as ILC=30mA

for an extended period of time may damage the device.

2. Internal supply current measured over VP_IO pin, by forcing internal digital supply to 2.0V, and applying 13.56 MHz alternative

pulses with amplitude 3.0Vpp to LC1 and LC2.

3. See Figure 11.

4. See Figure 12.
