Product Summary

The LTC1473CGN#TR is a Dual PowerPathTM Switch Driver. The LTC1473CGN#TR provides a power management solution for single and dual battery notebook computers and other portable equipment. The LTC1473CGN#TR drives two sets of backto-back N-channel MOSFET switches to route power to the input of the main system switching regulator. An internal boost regulator provides the voltage to fully enhance the logic level N-channel MOSFET switches. The applications of the LTC1473CGN#TR include Notebook Computers, Portable Instruments, Handi-Terminals, Portable Medical Equipment, Portable Industrial Control Equipment.
