LTC4417CUF#PBF

OR Controllers, Ideal Diodes Overview

The LTC4417CUF#PBF is a supply prioritizer from Analog Devices designed to manage multiple power sources. It selects the highest priority valid input among three channels, defined by pin configuration, to connect to a common output. The device operates within a wide voltage range of 2.5 V to 36 V and includes -42 V battery reverse protection. Key electrical characteristics include a low operating current of 28 µA and quiescent current less than 1 µA when below VOUT by 1.5%. It features fast non-overlapping switching to prevent cross-conduction and reverse currents, with a 6 V gate driver clamp for MOSFET protection. The component supports adjustable over-voltage and under-voltage hysteresis and utilizes a 16-lead QFN package.
