LTC4417HUF#PBF

OR Controllers, Ideal Diodes Overview

The LTC4417HUF#PBF is a prioritized PowerPath controller manufactured by Analog Devices Inc. It arbitrates among three input supply rails, selecting the highest priority valid supply to power a load. The device operates within an input voltage range of 2.5 V to 36 V and features adjustable overvoltage and undervoltage thresholds. It utilizes a 24-lead QFN package and supports cascading for additional inputs.
