  DESIGN FEATURES New Standalone Linear
  Li-Ion Battery Chargers
  Introduction
  Rechargeable batteries are commonly
  used to power portable devices such as
  digital cameras, PDAs, mobile phones
  and MP3 players. A wall adapter is
  the most common source of charging
  power, but an increasing number of
  applications are tapping into available USB power. The LTC4061 and
  LTC4062 are specifically designed to
  charge single-cell lithium-ion batteries
  from either of these sources.
  Both devices use constant current/constant voltage algorithms to
  deliver up to 1A of charge current
  (programmable) with a final float voltage accuracy of ±0.35%. They include
  an internal P-channel power MOSFET
  and thermal regulation circuitry with
  no blocking diode or external sense
  resistor required—the basic charger
  circuit requires only two external
  components.
  The LTC4061 and LTC4062 include both programmable time and …
