TDA8037
Overview
The TDA8037 is the cost efficient successor of the established integrated contact smart card reader IC TDA8035. 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 protection on all card contacts
- VCC regulation:; 3 V 5 % on 2 220 nF multilayer ceramic capacitors with low ESR; Current spikes of 40 nA 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, VDDhost, VREG and VDD dropping
- 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 (with SO28 package only)
- 2 Easy integration into your contact reader
- SW compatible to TDA8024, TDA8034 and TDA8035
- 3 V smart card supply
- Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8)
