LTC4415IDHC#PBF

OR Controllers, Ideal Diodes Overview

The LTC4415IDHC#PBF is a dual ideal diode controller manufactured by Analog Devices Inc., housed in a 16-lead DFN package measuring 3x5 mm with an exposed pad. It integrates two independent PowerPath controllers, each capable of sourcing up to 4A with a typical forward conduction resistance of 50mΩ. The device regulates voltage drops to 15mV during low-current forward conduction and limits reverse current to less than 1µA. Operating supply voltage ranges from 1.7V to 5.5V, with adjustable current limits from 0.5A to 4A via external resistors.

OR Controllers, Ideal Diodes Feature Summary

• Integrates two monolithic PowerPath ideal diodes for independent source selection and ORing applications
• Regulates forward voltage drop to 15mV at low currents to prevent oscillations during supply switchover
• Features independently enabled channels with prioritization inputs for flexible power path management
