LTC1755 General Description
The LTC®1755 universal Smart Card interface is fully compliant with ISO 7816-3 and EMV specifications. It provides the smallest and simplest interface circuit between a host microcontroller and general purpose Smart Cards.
An internal charge pump DC/DC converter delivers regulated 3V or 5V to the Smart Card, while on-chip level shifters allow connection to a low voltage controller. All Smart Card contacts are rated for 10kV ESD, eliminating the need for external ESD protection devices.
Input voltage may range from 2.7V to 6.0V, allowing direct connection to a battery. Automatic DC/DC converter soft start mitigates start-up problems that may result when the input power is provided by another regulator. Multiple LTC1755 devices may be paralleled and connected to a single controller for multicard applications.
Battery life is maximized by 60mA operating current and 1mA shutdown current. The 24-pin SSOP package minimizes PCB area for compact portable systems.
