Remark: The value of period T is 64 times the period interval of the internal oscillator (i.e.
± 25 μs).

120 mA. This detection is internally filtered, enabling spurious current pulses up to
200 mA with a duration of a few milliseconds to be drawn by the card without causing
deactivation. However, the average current value must stay below maximum; see
The following conditions are monitored by the fault detection circuit:
Fault detection monitors two different situations:

Overheating
Outside card sessions, pin CMDVCCN is HIGH: pin OFFN is LOW if the card is not in
the reader and HIGH if the card is in the reader. Any voltage drop on V
by the voltage supervisor. This generates an internal power-on reset pulse but does
not act upon the pin OFFN signal. The card is not powered-up and short-circuits or
overheating are not detected.
