LTC4415IMSE#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4415IMSE#TRPBF is a specialized power management integrated circuit from Analog Devices, featuring two monolithic PowerPath ideal diodes. Each channel supports up to 4A of current with a typical forward conduction resistance of 50mΩ. The device regulates voltage drops to 15mV during low-current forward conduction, ensuring stable operation and preventing oscillations during supply switchover. It exhibits less than 1µA reverse current flow, making it suitable for ORing applications. Independent enable inputs (EN1, EN2) allow prioritization, while adjustable current limits range from 0.5A to 4A via external resistors on CLIM pins.
