  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 systems—in addition to the EMV (Europay, MasterCard,
  Visa) and ISO7816 standards—by RST
