TDA8035HN
Overview
The TDA8035 is the cost efficient successor of the well established integrated contact smart card reader IC TDA8024. It offers a high level of security for the card performing current limitation, short circuit detection, ESD protection as well as supply supervision.
- 1 Protection of the contact smart card
- Thermal and short-circuit protections 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 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
