TDA8035HN/C1,157

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.

Protection of the contact smart card

• Thermal and short-circuit protections on all card contacts
• V_CC 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 (V_CC = 5 V and 3 V) or 15 nA/s (V_CC = 1.8 V) up to 20 MHz, with controlled rise and fall times, filtered overload detection 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 V_REG V_DD(INTF),V_DDP
• 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

Easy integration into your contact reader

• SW compatible to TDA8024 and TDA8034
