TDA8037: Low power 3V smart card interface
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. It is therefore the ideal component for a power efficient contact reader.
