The TDA8035 is the cost efficient successor of the established integrated contact smartcard reader IC TDA8024. It offers a high level of security for the card by performingcurrent limitation, short-circuit detection, ESD protection as well as supply supervision.The current consumption during the standby mode of the contact reader is very low as itoperates in the 3 V supply domain. The TDA8035 is therefore the ideal component for apower efficient contact reader.
