LTC4368HDD-1#WTRPBF

Surge Suppression ICS Overview

The LTC4368HDD-1#WTRPBF is a board-mount surge protector manufactured by Analog Devices Inc. It functions as a 100V undervoltage (UV), overvoltage (OV), and reverse protection controller equipped with a bidirectional circuit breaker. The device operates within an input voltage range of 2.5 V to 60 V and supports surface mount installation in a 10-WFDFN package with exposed pad. It is designed for automotive, industrial, energy storage, and portable instrumentation applications.

Surge Suppression ICS Feature Summary

• Provides comprehensive protection against input voltages that are too high, too low, or negative.
• Features a bidirectional circuit breaker to protect circuits from overcurrent faults in both forward and reverse directions.
• Controls the gate voltage of two back-to-back connected external MOSFETs to isolate the load during fault conditions.

Surge Suppression ICS Applications

• Automotive systems
• Industrial equipment
• Energy storage systems
• Portable instrumentation

Surge Suppression ICS Procurement Notes

Verify the specific suffix #WTRPBF indicates tape and reel packaging when ordering. Confirm the component meets AEC-Q100 qualification requirements if intended for automotive use. Ensure the design accommodates the 10-WFDFN footprint and exposed thermal pad for proper mounting and heat dissipation.

Surge Suppression ICS Selection Notes

Select this component for designs requiring robust protection against bidirectional current surges and abnormal input voltage conditions. It is suitable for applications needing adjustable UV and OV thresholds via external resistive dividers. Consider the external MOSFET requirement for handling the specific load current and voltage ratings.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 series of Surge Stoppers. It shares functional similarities with other variants like the IMS and IDD packages but differs in physical form factor. The device integrates control logic for external switches rather than containing internal power FETs, offering flexibility in system design.

Surge Suppression ICS Replacement Considerations

LTC4368HDD-1#PBF is a tube-packaged equivalent of the same electrical specification. Other package variants such as LTC4368IMS-1 or LTC4368IDD-1 offer identical functionality with different footprints.

Surge Suppression ICS FAQ

How are the overvoltage and undervoltage protection levels adjusted?

The OV and UV protection levels are adjusted using resistive dividers connected to the respective OV and UV pins on the controller.

What type of external components does the LTC4368 control?

The controller manages the gate voltage of two back-to-back connected external N-channel MOSFETs to ensure the load is disconnected during faults.
