LTC4368CMS-1#PBF

Surge Suppression ICS Overview

The LTC4368CMS-1#PBF is a board mount surge protector manufactured by Analog Devices Inc. It functions as a 100V undervoltage (UV), overvoltage (OV), and reverse protection controller featuring a bidirectional circuit breaker. The device operates within a voltage rating of 2.5 V to 60 V and has a current rating of 30 uA. It is housed in an MSOP-10 package with SMD/SMT termination. The component supports a minimum operating temperature of -40 C and a maximum operating temperature of +85 C.

Surge Suppression ICS Feature Summary

• Provides comprehensive protection against input voltages that are too high, too low, or negative.
• Controls gate voltage of external back-to-back MOSFETs to isolate the load during faults.
• Offers bidirectional circuit breaker functionality for overcurrent protection in both directions.

Surge Suppression ICS Applications

• Automotive systems
• Industrial equipment
• Energy storage applications
• Portable instrumentation

Surge Suppression ICS Procurement Notes

Verify availability status prior to ordering, as supply may be limited or subject to factory special orders. Confirm the specific suffix matches the required package and temperature range. Ensure compatibility with external MOSFET selection for the bidirectional circuit breaker implementation. Review the datasheet for resistor divider configurations required to set UV and OV thresholds accurately.

Surge Suppression ICS Selection Notes

Select this component when protection against bidirectional overcurrent and extreme input voltage conditions is required. The MSOP-10 package suits space-constrained designs. Verify that the external MOSFETs selected can handle the expected fault currents and voltage ratings. Consider the adjustable UV/OV limits via external resistors for precise system threshold configuration.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 family of surge stoppers designed for robust power path management. It integrates control logic for external switches rather than containing internal pass transistors. The family includes variants with different packages and temperature ranges, such as the IDD and IMS series, offering flexibility for various board layout and environmental requirements.
