LTC4419CDD#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4419CDD#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 utilizes external N-channel MOSFETs for efficient power path control. Unlike diode-OR products, it draws minimal current from the inactive supply even if its voltage exceeds that of the active supply. The component is housed in an 8-pin DFN package and supports logic interfaces down to 1.8V.
