■ ■ The LTC ®1479 is the “heart” of a total power management
solution for single and dual battery notebook computers
and other portable equipment. The LTC1479 directs power
from up to two battery packs and a DC power source to the
input of the main system switching regulator. It works in
concert with related LTC power management products
(e.g. LTC1435, LT В®1511, etc.) to create a total system
solution; starting from the batteries and the DC power
source, and ending at the input of each of the computer’s
complex loads. A system-provided power management
ВµP monitors and actively directs the LTC1479. Complete Power Path Management for Two
Batteries, DC Power Source, Charger and Backup
Compatible with Li-Ion, NiCd, NiMH and Lead-Acid
