LTC1479

PowerPath Controller

for Dual Battery Systems

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.
