LTC4413EDD-1#PBF

OR Controllers, Ideal Diodes Overview

The LTC4413EDD-1#PBF is a dual ideal diode controller manufactured by Analog Devices Inc., housed in a 10-pin, 3mm x 3mm DFN package. It integrates two independent monolithic ideal diodes capable of supplying up to 2.6A output current from input voltages ranging between 2.5V and 5.5V. Each channel utilizes an internal P-channel MOSFET with a low on-resistance of 100mΩ. The device regulates the forward voltage drop to approximately 18mV during standard operation and limits reverse leakage current to less than 1μA when the output exceeds the input. Static current consumption remains below 80μA at currents up to 1A. Internal circuitry provides both constant current limiting at 2.6A and thermal protection for fault conditions.

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix #PBF indicates tube packaging rather than tape and reel when sourcing components. Confirm availability status as distribution channels may list limited stock or factory special orders. Ensure the ordering part number matches the exact -1 variant to guarantee correct pinout and functional configuration relative to the -2 version which includes overvoltage protection features not present in this model.

OR Controllers, Ideal Diodes Selection Notes

Select this component when designing dual-channel power paths requiring high efficiency without external Schottky diodes. The LTC4413EDD-1#PBF is suitable for applications needing fast response times and low quiescent current. Choose this variant over the -2 version if overvoltage protection sensors are unnecessary for the design. Consider the 100mΩ on-resistance and 2.6A current limit when calculating thermal dissipation and trace widths for the PCB layout.

OR Controllers, Ideal Diodes Part Context

This device belongs to the LTC4413 family of ideal diode controllers designed for space-constrained portable electronics. It serves as a low-loss alternative to traditional diode ORing configurations. The family includes variants like the LTC4413-2 which adds overvoltage protection, and other related models such as the LTC4414 and MAX5079. The DFN package allows for minimal footprint usage while maintaining robust performance standards for professional power management applications.
