Vpc A card deactivation sequence is forced upon fault detected by an overcurrent condition or card removal event The voltage regulator can provide a card current of 65 mA in compliance with EMV 4 1 for 3 V and 5 V cards and 40 mA for 1 8 V cards The signals CMDVCCS and CMDVCC5 control the turn on output voltage value and turn off of Vcc When either signal is asserted low Vcc will ramp to the selected value or if both signals are asserted low within 400ns of each other Vcc will ramp to 1 8 V These signals are edge triggered If CMDVCC5 is asserted low to command Vcc to be 5 V and at a much later time greater than 2 us typically CMDVCC3 is asserted low it will be ignored and vice versa At the assertion low of either or both CMDVCC 3 5 signals Vcc will rise to the requested value When Vcc rises to an acceptable value and stays above that value for approximately 20 us RDY will be set high Approximately 510 us after the fall of CMDVCC 3 5 the circuit will check the see if Vcc is at or above the required minimum value indicated by RDY 1 and if not will begin an emergency deactivation sequence During the 510 us time card removal or de assertion of CMDVCC 3 5 shall also initiate an emergency deactivation sequence The circuit provides over current protection and limits Icc to 150 mA maximum for self protection When an over current condition is sensed the circuit will invoke a de activation sequence
