LTC4368CDD-2#PBF

Surge Suppression ICS Overview

The LTC4368CDD-2#PBF is a board mount surge protector manufactured by Analog Devices Inc. It functions as an undervoltage (UV), overvoltage (OV), and reverse protection controller with bidirectional circuit breaker capabilities. The device operates within a voltage range of 2.5 VDC to 60 VDC and features a quiescent current rating of 100 uA. It is housed in a DFN-10 surface-mount package measuring 3 mm in length, 3 mm in width, and 0.75 mm in height. The component supports a commercial operating temperature range from 0°C to +70°C.

Surge Suppression ICS Feature Summary

• Controls gate voltage of external back-to-back MOSFETs to isolate loads during fault conditions
• Provides bidirectional protection against overcurrent, overvoltage, undervoltage, and reverse polarity
• Features adjustable UV and OV thresholds via resistive dividers on dedicated pins

Surge Suppression ICS Applications

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

Surge Suppression ICS Procurement Notes

Verify availability status carefully as the part may be subject to limited supply or factory special order constraints. Confirm that the specific suffix matches the required commercial temperature grade and package variant for your design. Ensure compatibility with external MOSFET selection for the intended current ratings.

Surge Suppression ICS Selection Notes

Select this component when bidirectional surge protection and precise voltage threshold control are required for input power lines. Consider the DFN-10 package dimensions for PCB layout constraints. Verify that the external MOSFETs selected can handle the maximum expected fault currents and voltage levels specified for the application environment.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 series of surge stoppers designed for high-voltage input protection. It complements other variants like the IDD and HDD models which offer extended industrial and automotive temperature ranges. The CDD suffix specifically denotes the commercial temperature grade and DFN-10 package configuration.

Surge Suppression ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the LTC4368IDD-2#PBF or LTC4368HDD-2#PBF if wider temperature ranges are required, noting differences in operating specifications.
