  L DESIGN FEATURES Feature-Packed Charger Handles
  All Battery Chemistries and Produces
  3A/50W for Fast Charging from a
  4mm Г— 4mm QFN
  by James A. McKenzie
  Introduction
  The LTC4009, LTC4009-1 and
  LTC4009-2 are a family of high power
  battery charger ICs that achieve a small
  circuit size and high performance without compromising functionality. The
  family operates with high efficiency
  while packing the most desirable
  charging and protection features into
  a space-efficient 20-lead 4mm Г— 4mm
  QFN package. When combined with
  just a few external components and
  termination control, the LTC4009
  family facilitates construction of
  chargers capable of delivering up to
  3A to batteries with output power
  levels approaching 50W. These ICs are especially well-suited to implementing
  microprocessor-controlled chargers
  for all chemistry types, including …
