LTC4364IDE-2#PBF

Overview

The LTC4364IDE-2#PBF is an automotive-grade surge stopper with an integrated ideal diode controller, manufactured by Analog Devices Inc. It operates within a 4 VDC to 80 VDC input range and utilizes a 14-pin DFN package measuring 4 mm x 3 mm x 0.75 mm. The device supports SMD/SMT mounting and functions across a temperature range of -40°C to +85°C. Designed for high-voltage protection, it features adjustable output clamping and reverse voltage protection up to -40V on the input and -20V on the output. The component is AEC-Q100 qualified for automotive applications.

Feature Summary

• Provides overvoltage surge clamping and adjustable fault timer functionality
• Integrates ideal diode control to maintain downstream power during input drops
• Delivers reverse polarity protection for both input and output terminals

Applications

• Automotive and avionics surge protection systems
• Hot-swap and redundant power ORing circuits
• Output port protection in industrial equipment
• Power distribution networks in humanoid robots

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing from distributors. Confirm AEC-Q100 qualification status matches project requirements. Ensure the DFN-14 footprint aligns with PCB layout constraints. Cross-reference datasheet revisions for any recent product change notifications affecting pinout or electrical characteristics.

Selection Notes

Select this component for applications requiring robust protection against high-voltage transients exceeding standard operating limits. The integrated ideal diode feature reduces conduction losses compared to traditional Schottky solutions. Consider the adjustable clamping voltage for precise system protection thresholds. Verify thermal performance within the specified -40°C to +85°C operational range.

Part Context

This part belongs to the LTC4364 series of surge suppressors designed for board-mount protection. It complements other variants like the LTC4364CS-2#PBF and LTC4364HMS-2#PBF, which offer different temperature grades or package options. The IDE-2 designation specifically denotes the extended industrial/automotive grade with the DFN-14 form factor.

Replacement Considerations

LTC4364CS-2#PBF offers similar functionality with a commercial temperature range. LTC4364CDE-2#PBF provides an alternative DFN package variant. LTC4364HMS-2#PBF serves as a higher temperature grade option in an MSOP-16 package.
