The TDA8035 is the cost efficient successor of the established integrated contact smart
card reader IC TDA8024. It offers a high level of security for the card by performing
current limitation, short-circuit detection, ESD protection as well as supply supervision.
The current consumption during the standby mode of the contact reader is very low as it
operates in the 3 V supply domain. The TDA8035 is therefore the ideal component for a
power efficient contact reader.
Thermal and short-circuit protection on all card contacts
VCC regulation:
5 V, 3 V, 1.8 V ± 5 % on 2 × 220 nF multilayer ceramic capacitors with low ESR
current spikes of 40 nA/s (VCC = 5 V and 3 V) or 15 nA/s (VCC = 1.8 V) up
to 20 MHz, with controlled rise and fall times, filtered overload
detection is approximately 120 mA
Automatic activation and deactivation sequences initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, falling VREG VDD(INTF),VDDP
Enhanced card-side ElectroStatic Discharge (ESD) protection of (> 8 kV)
Supply supervisor for killing spikes during power on and off:
threshold internally fixed
externally by a resistor bridge
