LTC4368IDD-1#TRPBF

Surge Suppression ICS Overview

The LTC4368IDD-1#TRPBF 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 a voltage range of 2.5 V to 60 V and features a quiescent current rating of 30 uA. Designed for surface mount technology, it utilizes a DFN-10 package. The component supports an operating temperature range from -40°C to +85°C.

Surge Suppression ICS Feature Summary

• Provides comprehensive protection against input voltage anomalies including undervoltage, overvoltage, and negative polarity conditions.
• Integrates a bidirectional circuit breaker to manage overcurrent faults in both forward and reverse directions.
• Controls external back-to-back MOSFETs to isolate the load from the power supply during fault conditions.

Surge Suppression ICS Applications

• Automotive electronic systems requiring robust power line protection
• Industrial equipment needing reliable surge suppression
• Circuits susceptible to reverse polarity or voltage transients

Surge Suppression ICS Procurement Notes

Verify availability status carefully as this part number may be subject to limited supply or factory special order constraints. Confirm that the DFN-10 package matches your PCB footprint requirements. Ensure the 2.5 V to 60 V operating range aligns with your system's power specifications before finalizing procurement decisions.

Surge Suppression ICS Selection Notes

Select this component when bidirectional current protection and precise UV/OV control are required. The IDD suffix indicates the specific DFN-10 package variant. Consider the 30 uA quiescent current for low-power applications. Verify compatibility with external MOSFET gate drive capabilities and ensure the thermal performance meets the -40°C to +85°C operational envelope.

Surge Suppression ICS Part Context

This component belongs to the LTC4368 family of surge stoppers designed for high-reliability power management. It serves as a specialized IC for protecting sensitive electronics from severe power line disturbances. The device complements other Analog Devices power protection solutions by offering integrated bidirectional breaking capabilities alongside standard voltage regulation monitoring.

Surge Suppression ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative models within the LTC4368 series based on package compatibility and pin configuration. Verify functional equivalence regarding bidirectional circuit breaker thresholds and UV/OV trigger levels before substitution.
