Description

The TDA8034HN is a highly integrated, cost-effective analog interface IC designed to connect asynchronous and synchronous smart cards to a host microcontroller. Supporting 5 V, 3 V, and 1.8 V card operation, the device provides all essential supply, control, and protection functions while requiring minimal external components. It ensures reliable interfacing by managing card activation/deactivation, short-circuit protection, over-current protection, and thermal shutdown—ensuring both the card and host system remain safe during operation. This makes the TDA8034HN ideal for secure identification, payment terminals, access control, and SIM card interfaces in communication systems. Its compact and simplified design reduces BOM cost and speeds up product development.
