LTC4364CMS-2#PBF

Overview

The LTC4364CMS-2#PBF is a board-mount surge stopper with ideal diode control manufactured by Analog Devices Inc. It operates within a wide voltage range of 4V to 80V and protects downstream circuits from overvoltage, overcurrent, reverse input, and reverse output conditions. The device drives an external N-channel MOSFET to function as an ideal diode, reducing power loss compared to Schottky diodes. It features adjustable output clamping voltage, fault timers, and status indication. The component supports high transient surge withstand capabilities up to 200V when paired with appropriate external components.

Feature Summary

• Ideal diode controller functionality for low-loss power path management
• Integrated protection against overvoltage, overcurrent, and reverse polarity events
• Adjustable output clamping voltage and fault timer settings
• High transient surge withstand capability via external MOSFET drive

Applications

• Automotive and avionics surge protection
• Hot-swap and live-insertion applications
• Redundant power OR-ing configurations
• Output port protection in industrial systems

Procurement Notes

Verify the specific suffix CMS-2 corresponds to the intended retry duty cycle configuration (0.1%) before procurement. Confirm package type matches design requirements. Check current supply status as availability may be restricted. Ensure external MOSFET selection aligns with voltage and current ratings specified in the datasheet for optimal performance.

Selection Notes

Select this component for applications requiring robust protection against electrical transients and reverse polarity. The -2 suffix indicates specific fault retry behavior suitable for sensitive loads. Consider thermal management requirements for the external MOSFET. Evaluate the need for adjustable clamping voltages versus fixed protection thresholds. Ensure compatibility with system operating voltage ranges between 4V and 80V.

Part Context

The LTC4364 series includes variants like LTC4364CS-1 and LTC4364IMS-1, differing primarily in package types such as SOIC-16 or MSOP-16 and retry behaviors. The CMS-2 variant specifically utilizes a Mini-SOIC package. These devices form part of Analog Devices' broader portfolio of circuit protection solutions designed for harsh environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and functional compatibility if considering alternative surge suppressors from other manufacturers.
