LTC4417IUF#PBF

OR Controllers, Ideal Diodes Overview

The LTC4417IUF#PBF is a dual-channel prioritized PowerPath controller designed to connect one of two valid power sources to a common output based on defined priority. V1 serves as the high-priority input, while V2 acts as the low-priority input. The device supports an operating supply range of 2.5V to 36V and withstands reverse voltages up to -42V. It features a low quiescent current of 28µA and operates within a temperature range of -40°C to +85°C. The component utilizes external FETs and is housed in a 20-lead 4mm x 4mm QFN package.

OR Controllers, Ideal Diodes Feature Summary

• Selects the highest priority valid power source from two inputs for connection to a common output
• Prevents reverse and cross-conduction currents using fast non-overlapping switching circuitry
• Provides battery reverse protection capable of withstanding -42V reverse voltage
• Includes a gate driver with a 6V clamp to protect external MOSFETs

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 against official Analog Devices documentation to confirm pinout and electrical characteristics match project requirements. Ensure the selected variant aligns with the required thermal performance and package constraints. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance and environmental ratings before finalizing procurement specifications.

OR Controllers, Ideal Diodes Selection Notes

Choose this component when system architecture requires automatic switchover between two power rails with strict priority enforcement. It is suitable for designs needing minimal output voltage drop during transitions and protection against reverse polarity. Consider cascading multiple units if more than two input sources require arbitration. Verify that external MOSFET gate drive limits are compatible with the internal 6V clamp.

OR Controllers, Ideal Diodes Part Context

This part belongs to the LTC441x family of PowerPath controllers, which manage power source selection and redundancy. Unlike single-channel solutions, this dual-channel variant allows for defined priority logic between V1 and V2. It complements other family members like the LTC4418 by offering similar functionality in a specific package configuration optimized for space-constrained applications.

OR Controllers, Ideal Diodes Replacement Considerations

The LTC4418IUF#PBF is a confirmed substitute within the same product family. Both devices offer dual-channel prioritized power path control. Verify that the pinout compatibility and specific electrical parameters meet the design requirements before swapping components.
