At powerup, the CRD_VCC voltage rise time depends
upon the current capability of the DC/DC converter
associated with the external inductor L1 and the reservoir
capacitor connected across CRD_VCC and GROUND.
During this sequence, the average input current is 300 mA
typical (Figure 4), assuming the system is fully loaded
during the startup. Finally, the application software is
responsible for the smart card signal sequence.
On the other hand, at turn off, the CRD_VCC fall time
depends upon the external reservoir capacitor and the peak
current absorbed by the internal NMOS transistor built
across CRD_VCC and GROUND. These behaviors are
depicted in Figure 5.
Since these parameters have finite values, depending
upon the external constraints, the designer must take care of
these limits if the tON or the tOFF provided by the data sheets
does not meet his requirements.
