  DESIGN IDEAS Decrease Li-Ion Battery Charge
  Time with a Monolithic Charger that
  by Phil Juang
  Prevents Overheating
  Introduction
  The LTC4054 is a constant-current/
  constant-voltage linear battery charger
  with an internal power MOSFET in
  a tiny ThinSOT package. Most linear
  chargers risk temporary, excessive
  power dissipation and possible
  overheating, but the LTC4054 uses
  internal thermal feedback to regulate
  the charge current and limit the die
  temperature to 120В°C. This feature
  allows the designer to program the
  LTC4054 to higher charge currents
  with the assurance that the LTC4054
  will not overheat and damage itself or
  other components. This article shows
  how to use the LTC4054 to maximize
  the thermally regulated charge current
  to reduce battery charging times. …
