DESIGN IDEAS Smart Card Interfaces Made Easy
by Steven Martin Introduction
Smart Card interfaces must comply
with extensive, and often difficult,
software and hardware standards
to produce robust card reading systems. The LTC4556 makes it easy to
comply with Smart Card interface
requirements by integrating all required power management, control,
ESD and fault protection circuitry into
a single device, precluding the need
for a complicated array of discrete
components.
The LTC4556 employs a voltage
doubling charge pump and a low
dropout linear regulator to generate
an output voltage of 5V, 3V or 1.8V
from a 2.7V to 5.5V input. It supports
custom Smart Card systemsвЂ”in addition to the EMV (Europay, MasterCard,
Visa) and ISO7816 standardsвЂ”by RST
