LTC4419IMSE#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4419IMSE#TRPBF is a dual-input monolithic PowerPath prioritizer manufactured by Analog Devices Inc. It provides backup switchover functionality to maintain critical circuit operation during brown-out and power loss conditions. The device features low operating current and interfaces with low-voltage logic. Unlike diode-OR products, it draws minimal current from the inactive supply even if its voltage exceeds that of the active supply. The component operates within an input voltage range of 1.8V to 18V and is housed in a 12-pin MSOP EP package.

OR Controllers, Ideal Diodes Feature Summary

• Provides automatic backup switchover for critical circuitry during power loss or brown-out events
