LTC4417CGN#PBF

OR Controllers, Ideal Diodes Overview

The LTC4417CGN#PBF is a supply prioritizer manufactured by Analog Devices Inc., designed to select the highest priority active power source from up to three inputs and route it to a common output. It operates within a wide input voltage range of 2.5 V to 36 V and features a narrow SSOP-24 package. The device includes integrated P-channel MOSFETs with gate drive protection, controlled output ramping to minimize inrush current, and fast non-overlapping switching to prevent reverse and cross-conduction currents. It supports cascading for additional inputs and provides adjustable over-voltage and under-voltage hysteresis.
