LTC1479  
PowerPath Controller  
for Dual Battery Systems  
U
DESCRIPTION  
FEATURES  
The LTC®1479 is the “heart” of a total power management  
solution for single and dual battery notebook computers  
andotherportableequipment.TheLTC1479directspower  
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®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  
µP 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  
■
Battery Chemistries  
■
“3-Diode” Mode Ensures Powers is Available  
under “Cold Start” Conditions  
■
All N-Channel Switching Reduces Power Losses  
■
Capacitor and Battery Inrush Current Limited  
■
“Seamless” Switching Between Power Sources  
■
Independent Charging and Monitoring of Two  
Battery Packs  
■
New, Small Footprint, 36-Lead SSOP Package  
The LTC1479 uses low loss N-channel MOSFET switches  
to direct power from three main sources. An adaptive  
current limiting scheme reduces capacitor and battery  
inrush current by controlling the gates of the MOSFET  
switches during transitions. The LTC1479 interfaces di-  
rectly to the LT1510, LT1511 and LT1620/LTC1435 bat-  
tery charging circuits.
