LTC4368HMS-1#PBF

Surge Suppression ICS Overview

The LTC4368HMS-1#PBF is a board mount surge protector and reverse protection controller manufactured by Analog Devices Inc. It operates within a voltage range of 2.5 VDC to 60 VDC and features an MSOP-10 surface-mount package measuring 3 mm x 3 mm with a height of 0.86 mm. The device supports bidirectional circuit breaker functionality, protecting against overvoltage, undervoltage, negative supply voltages, and forward or reverse overcurrent faults. It functions as an external switch driver for high-side NMOS transistors.

Surge Suppression ICS Feature Summary

• Provides comprehensive protection against power supply anomalies including excessive voltage, insufficient voltage, and negative potentials.
• Integrates bidirectional circuit breaker capabilities to manage overcurrent faults in both forward and reverse current directions.
• Functions as a high-side static switch driver utilizing external N-channel MOSFETs for efficient power path control.

Surge Suppression ICS Applications

• Automotive electronic systems requiring robust power input protection
• Industrial equipment power distribution networks
• Energy storage system input stages
• Portable instrumentation power management

Surge Suppression ICS Procurement Notes

Verify the specific suffix designation when ordering, as packaging and tape/reel configurations may vary between #WPBF and #TRPBF variants. Confirm that the MSOP-10 package aligns with the target PCB footprint and thermal requirements. Ensure the selected variant meets the required operating temperature range for the intended application environment before finalizing procurement.

Surge Suppression ICS Selection Notes

Select this component when designing circuits requiring protection against both positive and negative overcurrent conditions alongside voltage supervision. The device is suitable for applications needing low quiescent current operation while managing high-side switching. Consider the external MOSFET selection carefully to ensure compatibility with the controller's drive capabilities and the expected fault current levels.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 family of Surge Stoppers, which are designed to protect sensitive downstream electronics from abusive power supply conditions. The series includes various packages and pinout configurations to accommodate different design constraints. The HMS-1 variant specifically utilizes the MSOP-10 package format, distinguishing it from DFN or other form factors within the same functional family.

Surge Suppression ICS Replacement Considerations

LTC4368HMS-1#WPBF serves as a direct alternative with identical electrical specifications but differs in packaging configuration. Other variants within the LTC4368 family may offer different pinouts or package types such as DFN-10, requiring schematic and layout verification before substitution.
