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. Operating in 3 V supply domain, the current consumption during the shutdown mode of the contact reader is very low.
TDA8037 Key Features
- 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
- Automatic activation and deactivation sequences initiated by software or by hardware
- 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)
- SW patible to TDA8024, TDA8034 and TDA8035
