Each card is supplied by a separate V
buffers are supplied by the same multimode capacitive
DC-to-DC converter.
In all modes (follower, doubler and tripler), the DC-to-DC
converter is able to deliver 80 mA over the whole V
range (2.7 to 6.5 V) or 120 mA if V

capacitor with a value of between 100 and 200 nF. If the
card socket is not very close to the device, one capacitor
should be connected close to the device, and a second
one connected close to card contact C1.
Protections
The current on pin CLK is limited to within the range
+70 mA and 70 mA.
The current on pin RST is limited to within the range
+20 mA and 20 mA; if the current reaches this value with

In the event of overcurrent on V
session, overheating, or overcurrent on RST, then the
TDA8020HL performs an automatic emergency
deactivation sequence on the corresponding card, resets
bit START/STOP and pulls pin IRQ LOW.
In the event of overheating or supply drop-out, or
DC-to-DC converter out of specification, the TDA8020HL
performs an automatic emergency deactivation sequence
on both cards, resets both bits START/STOP and pulls
pin IRQ LOW.
