LTC4368IMS-2#PBF

Surge Suppression ICS Overview

The LTC4368IMS-2#PBF is a board mount surge protector manufactured by Analog Devices Inc., housed in an MSOP-10 surface-mount package measuring 3 mm x 3 mm with a height of 0.86 mm. It functions as a reverse protection controller with a bidirectional circuit breaker, rated for input voltages from 2.5 V to 60 V and quiescent current of 30 uA. The device operates within a temperature range of -40°C to +85°C and provides undervoltage, overvoltage, and reverse voltage protection.

Surge Suppression ICS Feature Summary

• Controls external back-to-back MOSFETs to isolate loads during voltage or current faults
• Provides bidirectional circuit breaker functionality against overcurrent conditions
• Features adjustable undervoltage and overvoltage thresholds via resistive dividers

Surge Suppression ICS Applications

• Automotive power distribution systems
• Industrial equipment power inputs
• DC/DC converter input stages

Surge Suppression ICS Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free compliance when sourcing. Confirm the 'IMS-2' designation matches the required pinout and threshold configuration for the design. Ensure the MSOP-10 footprint aligns with PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any potential form-fit-function updates.

Surge Suppression ICS Selection Notes

Select this component for applications requiring robust protection against reverse polarity and transient voltage spikes up to 60V. The integrated bidirectional breaker simplifies design compared to discrete solutions. Consider the low quiescent current for efficiency-sensitive designs. Verify that external MOSFET selection supports the expected load currents and thermal requirements.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 family of Surge Stoppers, designed to protect sensitive electronics from abusive power supply conditions. Unlike standard TVS diodes, it actively controls external switches to disconnect the load, offering superior protection against sustained overvoltage and reverse connections while managing bidirectional fault currents.

Surge Suppression ICS Replacement Considerations

The LTC4368IMS-2#WPBF is a verified alternative variant within the same family, differing primarily in packaging or compliance specifications. Both share identical functional characteristics and pinouts.
