  DESIGN FEATURES Smart Battery Charger Is
  Programmed via the SMBus by Mark Gurries Introduction
  Smart Batteries are becoming prevalent in the laptop computer world
  because they offer an industry-standard, high accuracy “gas gauge”
  system. These batteries conform to a
  set of specifications that define the
  operation of all of the components in
  a Smart Battery powered System
  (SBS). The battery has an embedded
  controller that tracks information
  related to battery charging and use.
  This information is provided to the
  system via a serial, 2-wire SMBus
  interface, a variant of the I2Cв„ў bus in
  wide use today. The battery can be
  queried for information on remaining
  capacity, total capacity, time remaining at current rate of discharge,
  discharge current, terminal voltage
  and so on. Since most Smart Batteries can become a master on the bus,
  the battery can control the Smart
  Battery Charger for optimal charging.
  The LTC1759 Smart Battery Charger
  IC is designed to be controlled by this …
