描述 Description

The TDA8037 is the cost efficient successor of the established integrated contact smartcard reader IC TDA8035. It offers a high level of security for the card performing currentlimitation, short circuit detection, ESD protection as well as supply supervision. Operatingin 3 V supply domain, the current consumption during the shutdown mode of the contactreader is very low. It is therefore the ideal component for a power efficient contact reader.
