LTC4364CDE-1#TRPBF

Overview

The LTC4364CDE-1#TRPBF is a surge stopper integrated circuit from Analog Devices Inc., designed for overvoltage and reverse protection applications. It utilizes an external N-channel MOSFET to manage power delivery, offering bidirectional circuit breaker functionality. The device operates within a voltage range of 4VDC to 80VDC and features adjustable clamping capabilities. Packaged in a compact 14-DFN (3mm x 4mm) surface-mount case with a height of 0.75mm, it supports tape-and-reel distribution for automated assembly processes.

Feature Summary

• Integrates bidirectional circuit breaker control for robust fault management
• Utilizes external N-channel MOSFET for low on-resistance conduction
• Provides adjustable overvoltage and reverse polarity protection thresholds

Applications

• Automotive electronic systems requiring high-voltage surge protection
• Avionics power distribution networks needing reliable fault isolation
• Industrial equipment interfaces susceptible to transient voltage events

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required operating parameters. Confirm that the DFN package dimensions align with PCB footprint constraints. Cross-reference the manufacturer's latest product change notices to validate current manufacturing status and material specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring precise control over hot-swap and surge events using discrete MOSFETs. Ensure the external switch selection matches the current handling requirements defined by the controller's limit pins. Evaluate thermal dissipation needs based on the specific application's duty cycle and ambient temperature conditions.

Part Context

This part belongs to the LTC4364 family of wide operating range controllers. Variants within this series differ primarily in pinout configurations and specific threshold settings. The CDE-1 designation indicates a specific package type and internal reference configuration distinct from other suffixes like IMS or IS.

Replacement Considerations

Direct substitutes include LTC4364CDE-2#TRPBF for alternative threshold settings within the same package. Other family members such as LTC4364HDE-1#PBF offer similar functionality in different form factors.
