Introduction

The LTC4355 is an N+1 ORing controller designed to provide a robust, simple, and efficient mechanism for connecting redundant power supplies or batteries to a common load. It features an integrated N-channel MOSFET switch that automatically connects the higher voltage supply to the load, preventing reverse current flow from a failing supply. The LTC4355 offers adjustable turn-on and turn-off delays to prevent spurious switching during load transients.
