LTC4366HTS8-2#TRPBF

Surge Suppression ICS Overview

The LTC4366HTS8-2#TRPBF is a high voltage surge stopper manufactured by Analog Devices Inc., designed for board-mount protection applications. It operates within a supply voltage range of 9V to greater than 500V, utilizing an external N-channel MOSFET for control. The device features a hot-swap capability with adjustable current limit and includes a built-in 9-second cool-down timer following fault conditions. It is housed in an 8-pin TSOT-23 package and supports surface mount technology.

Surge Suppression ICS Feature Summary

• Utilizes a floating topology architecture to manage input voltages significantly higher than the internal circuitry limits
• Provides automatic retry functionality after transient overvoltage events without requiring manual intervention
• Integrates a fixed cool-down timer to prevent repeated stress on the power system during persistent faults

Surge Suppression ICS Applications

• Industrial automation systems requiring robust power line protection
• Automotive electronics exposed to load dump and harsh electrical environments
• Avionic equipment demanding high reliability against voltage transients

Surge Suppression ICS Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm that the specific suffix corresponds to the auto-retry variant rather than the latch-off version. Ensure the TSOT-23 footprint matches the design requirements before finalizing procurement orders.

Surge Suppression ICS Selection Notes

Select this model when automatic recovery from overvoltage surges is required without resetting the system. Compare against latch-off variants if permanent shutdown upon fault is preferred. Validate that the external MOSFET selection aligns with the voltage and current specifications of the target application.

Surge Suppression ICS Part Context

This component belongs to the LTC4366 series of high voltage surge stoppers. It shares the core floating topology with other variants but differs in its retry behavior and package type. The series addresses the limitations of traditional protection methods by allowing the controller to float above the protected rail.

Surge Suppression ICS Replacement Considerations

LTC4366IDDB-2#TRPBF offers similar auto-retry functionality in a DFN package. LTC4366MPDDB-2#TRMPBF provides the same features in a larger DFN format. Verify pin compatibility and thermal performance when substituting between different package types.
