LTC4368HMS-2#WTRPBF

Surge Suppression ICS Overview

The LTC4368HMS-2#WTRPBF is a board-mount surge protector and reverse protection controller manufactured by Analog Devices Inc. It operates within a voltage range of 2.5 V to 60 V and features an MSOP-10 surface-mount package measuring 3 mm x 3 mm with a height of 0.86 mm. Designed for automotive, industrial, and energy storage applications, the device functions across a temperature range of -40°C to +85°C. It provides undervoltage, overvoltage, and reverse polarity protection while incorporating a bidirectional circuit breaker to manage overcurrent faults in both forward and reverse directions.

Surge Suppression ICS Feature Summary

• Provides comprehensive protection against input voltages that are too high, too low, or negative.
• Integrates a bidirectional circuit breaker to handle overcurrent faults in both forward and reverse current 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
• Industrial equipment power inputs
• Energy storage system interfaces
• Portable instrumentation

Surge Suppression ICS Procurement Notes

Verify the specific suffix #WTRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and any distinct electrical tolerances compared to standard variants. Ensure compatibility with MSOP-10 footprint requirements and validate operating temperature ranges for the intended environment before finalizing procurement specifications.

Surge Suppression ICS Selection Notes

Select this component when bidirectional overcurrent protection is required alongside UV/OV safeguards. The MSOP-10 package suits space-constrained designs. Confirm that external MOSFET selection aligns with the controller's gate drive capabilities and that the application voltage remains within the 2.5 V to 60 V operational window.
