Linear Technology Magazine December 2009 Articles on LTC4099 and LTC2262
The first article, titled 'Battery Conditioner Extends the Life of Li-Ion Batteries' by George H. Barbehenn, describes the LTC4099 chip. It explains how an I²C controlled battery conditioner within the chip maximizes battery operating life by preventing aging caused by high voltage and temperature conditions. The text details the underlying aging process in Lithium-ion batteries and illustrates the LTC4099's discharge curve when protecting a battery above 60°C.

What is the function of the Bat-Track feature?
It keeps the output voltage approximately 300mV above the battery voltage to allow the charger to operate very efficiently.
How does the auxiliary regulator control work?
It detects an external high voltage buck regulator and controls its output to within approximately 300mV of the battery voltage.
What is the primary function of the LTC4099 battery conditioner?
The LTC4099 contains an I2C controlled battery conditioner that maximizes battery operating life while optimizing run time and charging speed.
