LTC4417IUF#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4417IUF#TRPBF is a PowerPath controller manufactured by Analog Devices Inc. It prioritizes three input power sources to a common output based on defined pin configurations, with V1 as highest priority and V3 as lowest. The device operates within a wide voltage range of 2.5 V to 36 V and includes -42 V battery reverse protection. It features fast non-overlapping switching to prevent cross-conduction and controlled output ramping to minimize inrush current. The component is housed in a 24-lead QFN package.

OR Controllers, Ideal Diodes Feature Summary

• Selects the highest priority valid input from three sources for a shared output
• Blocks reverse and cross-conduction currents using fast non-overlapping switching
• Includes a 6 V clamp on the gate driver to protect external MOSFETs
• Features a low quiescent supply current of less than 1 μA when below VOUT

OR Controllers, Ideal Diodes Applications

• Industrial handheld instruments
• High availability systems
• Battery backup systems
• Servers and computer peripherals

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix #TRPBF indicates reel packaging rather than tube. Confirm the I-grade temperature rating matches application requirements. Ensure the 24-lead QFN footprint aligns with PCB layout constraints. Validate that the 36 V maximum input voltage covers all potential source conditions.

OR Controllers, Ideal Diodes Selection Notes

Choose this part when multi-source redundancy with strict priority logic is required. The integrated MOSFET drivers reduce external component count compared to discrete solutions. Consider the thermal performance of the QFN package for high-current applications. Verify that the 256 ms validity window meets system startup timing requirements.

OR Controllers, Ideal Diodes Part Context

This component belongs to the LTC4417 family of PowerPath controllers designed for power management. It simplifies the design of redundant power systems by handling source selection automatically. The device integrates control logic and gate drivers, reducing board space and complexity compared to manual switching approaches.
