LTC1755 Overview
Key Features
- The parts provide the smallest and simplest interface circuits between a host microcontroller and general purpose Smart Cards
- 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
- Internal soft-start mitigates startup problems that may result when the input power is provided by another regulator
- Multiple devices may be paralleled and connected to a single controller for multicard applications
- Battery life is maximized by 60µA operating current and 1µA shutdown current
- The narrow SSOP packages minimize PCB area for compact portable systems
- LTC and LT are registered trademarks of Linear Technology Corporation
