LTC4368HDD-2#WTRPBF

Surge Suppression ICS Overview

The LTC4368HDD-2#WTRPBF is a board-mount surge protector and UV/OV reverse protection controller manufactured by Analog Devices Inc. It operates within a voltage range of 2.5 VDC to 60 VDC and features a supply current of 100 uA. The component is housed in a DFN-10 package with dimensions of 3 mm x 3 mm x 0.75 mm height, utilizing SMD/SMT termination. It supports an operating temperature range from -40°C to +125°C. This device provides bidirectional circuit breaker functionality and protects against overcurrent, overvoltage, undervoltage, and reverse polarity faults.

Surge Suppression ICS Feature Summary

• Provides bidirectional circuit breaker protection against overcurrent faults in both forward and reverse directions.
• Controls external back-to-back MOSFETs to disconnect the load during voltage or current faults.
• Offers adjustable undervoltage and overvoltage protection thresholds via external resistive dividers.

Surge Suppression ICS Applications

• Automotive systems requiring robust power input protection
• Industrial equipment needing reliable surge suppression
• Energy storage applications with variable input voltages
• Portable instrumentation demanding low quiescent current

Surge Suppression ICS Procurement Notes

Verify the specific suffix WTRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm availability as distribution channels may list limited stock or discontinuation notices. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design before finalizing procurement.

Surge Suppression ICS Selection Notes

Select this component when designing circuits that require integrated bidirectional surge protection and adjustable UV/OV control. It is suitable for applications where space is constrained due to its compact DFN-10 package. Consider the 100 uA supply current for low-power designs. Ensure external MOSFETs are selected to handle the expected fault currents and voltage ratings compatible with the 60 VDC maximum input.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 series of Surge Stoppers, which are designed to protect sensitive electronics from power supply anomalies. The series includes variants with different packages and suffixes. The LTC4368 family is widely used in automotive and industrial sectors for its ability to manage bidirectional current flow and provide precise voltage monitoring without internal switching elements.

Surge Suppression ICS Replacement Considerations

Check Analog Devices datasheets for direct substitutes within the LTC4368 family, such as the LTC4368HDD-2#PBF, noting any differences in packaging or suffix codes. Verify that alternative components maintain the same bidirectional protection capabilities and voltage ranges. Consult official replacement guides to ensure compatibility with existing PCB layouts and thermal requirements.
