  • High-Current/Short-Circuit and High-Temperature Protection

The DS8023 smart card interface IC is a low-cost, low-power, analog front-end for a smart card reader designed for all ISO 7816, EMV*, and GSM11-11 applications. The DS8023 supports 5V, 3V, and 1.8V smart cards, and provides an option for ultra-low stop-mode power consumption. The DS8023 is available in 28-pin TSSOP and SO packages, and can often be used as a replacement for the TDA8024 with little or no application changes.

The DS8023 is designed to interface between a system microcontroller and the smart card interface, providing all power supply, protection, and level shifting required for IC card applications.
