  LTC4099 Provides Unprecedented Control of USB Power
  Management and Battery Charger Functions Using I2C
  Design Note 1017
  George H. Barbehenn
  Introduction
  The LTC ®4099 high efficiency USB power manager and
  Li-Ion/Polymer battery charger seamlessly manages
  power distribution from multiple sources in portable
  applications. It is differentiated from other USB power
  managers by its bidirectional I2C port that allows the host
  microprocessor to control and monitor all aspects of the
  USB power management and battery charging processes.
  In addition, a programmable interrupt generation function
  alerts the host microprocessor to changes in device status
  and provides unprecedented control of power management functions. This high degree of configurability allows
  post-layout changes in operation, even changes in the
  field, and it allows a single qualified device to be used
  in a variety of products, thus reducing design time and
  easing inventory management.
  Many Desirable Features in a Small Package
  In addition to all of its power management functions,
  the LTC4099 includes overvoltage protection, auxiliary
  regulator control (to manage high voltage inputs), and an …

  DESIGN IDEAS L Battery Conditioner Extends the
  by George H. Barbehenn
  Life of Li-Ion Batteries
  Introduction
  Li-Ion batteries naturally age, with an
  expected lifetime of about three years,
  but that life can be cut very short—to
  under a year—if the batteries are mishandled. It turns out that the batteries
  are typically abused in applications
  where intelligent conditioning would
  otherwise significantly extend the
  battery lifetime. The LTC4099 battery
  charger and power manager contains
  an I2C controlled battery conditioner
  that maximizes battery operating life,
  while also optimizing battery run time
  and charging speed (see Figure 1). The Underlying Aging
  Process in Li-Ion Batteries Modern Li-Ion batteries are constructed of a graphite battery cathode,
  cobalt, manganese or iron phosphate
  battery anode and an electrolyte that
  transports the lithium ions.
  The electrolyte may be a gel, a
  polymer (Li-Ion/Polymer batteries) …
