LTC1479CG#PBF

LTC1479 is a PowerPath controller for dual battery systems. It is the “heart” of a total power management solution for single and dual battery notebook computers and other portable equipment. It 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 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. It 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. It is used in application such as notebook computer power management, portable instruments, handheld terminals, portable medical equipment, portable industrial control equipment etc.
