Introduction

The LTC4358CDE is an N+1 ORing controller that provides a simple, low-cost solution for implementing high-availability power systems. It features a low on-resistance N-channel MOSFET switch and a precise reference to control the on/off state of the switch. The LTC4358CDE is designed to be used in N+1 redundant power supply systems, where it ensures that the highest voltage supply is always connected to the load, while isolating lower voltage supplies.
