Smart-card analog front-end interface IC with ESD protection

The DS8024 from Maxim is a low-cost, smart card interface IC designed for all ISO 7816, EMV, and GSM 11.11applications. This device is designed to meet EMV 4.0 Level 1 requirements for smart-card communication. With a robust communication interface, the DS8024 performs level translation between a host microcontroller and a 5V or 3V. It provides ±8kV ESD (IEC) protection to prevent damage to the application during card insertion and removal. The DS8024 is ideal for use in financial terminals, consumer set-top boxes, and smart-card reader products.
Card activation and deactivation are handled with an internal sequencer for predictable application of signals and power to the smart card. Short-circuit and over-temperature detectors automatically shut down the power supply when a potentially dangerous situation is detected. It also supplies up to 80mA for smart-card operation. A drop-in upgrade for the TDA8024 and the ST8024.
