LS2405IDD23

OR Controllers, Ideal Diodes Overview

The LS2405IDD23 is an ideal diode controller from Littelfuse designed to emulate a 5A very low forward voltage diode. It operates within a wide input range of 2.7V to 24V and withstands surge voltages up to 28V. The device integrates a 35mΩ N-channel MOSFET, replacing traditional power Schottky diodes in high-current applications. Packaged in a compact 8-lead DFN (2mmx3mm) format, it ensures efficient power management with minimal conduction losses.

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific ordering suffix IDD23 confirms the 8-lead DFN 2mmx3mm package configuration. Ensure the application voltage does not exceed the 28V surge rating. Confirm that the 5A continuous current capability aligns with system requirements. Check for any specific thermal pad grounding requirements associated with the DFN package during assembly.

OR Controllers, Ideal Diodes Selection Notes

Select this component when replacing discrete Schottky diodes to improve efficiency through lower on-resistance. It is suitable for systems requiring precise current sharing or redundancy without the voltage drop penalty of standard diodes. Consider the 2.7V minimum operating voltage to ensure compatibility with low-voltage rails. Evaluate the 35mΩ MOSFET integration against external gate drive solutions for size constraints.

OR Controllers, Ideal Diodes Part Context

This device belongs to the LS2405 Series eFuse family from Littelfuse. These components are engineered as ideal diode controllers to optimize power distribution networks. The series focuses on reducing power loss and heat generation compared to passive rectification methods, offering a compact solution for modern electronic designs.

OR Controllers, Ideal Diodes Replacement Considerations

Direct substitutes include other ideal diode controllers with similar 5A ratings and 24V operation ranges. Verify pinout compatibility if replacing legacy Schottky diode setups with active solutions. Ensure the replacement supports the required 28V surge tolerance and offers comparable Rds(on) performance.
