Fault detection

The following fault conditions are monitored by the circuit:

• Short-circuit or high current on VCC

• Removing card during transaction

• VDD dropping

• Overheating.

When one or more of these faults are detected, the circuit

pulls the interrupt line OFF to its active LOW state and a

deactivation sequence is initiated. In case the card is

present the interrupt line OFF is set to HIGH when the

microcontroller has reset the CMDVCC line HIGH (after

completion of the deactivation sequence). In case the card

is not present OFF remains LOW.
