Smart Card Interface 10MHz 3.3V 0.1W1/10W T/R 16Pin TSSOP
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. It is therefore the ideal component for a power efficient contact reader.
