LTC4368HDD-1#WPBF

Surge Suppression ICS Overview

The LTC4368HDD-1#WPBF is a board mount surge protector manufactured by Analog Devices Inc. It functions as an overvoltage, undervoltage, and reverse protection controller with an adjustable external switch. The device operates within a voltage range of 2.5 VDC to 60 VDC and features a maximum supply current of 100 uA. It is housed in a surface-mount DFN-10 package measuring 3 mm x 3 mm with a height of 0.75 mm. The component supports an operating temperature range from -40°C to +125°C.

Surge Suppression ICS Feature Summary

• Provides integrated control for overvoltage, undervoltage, and reverse polarity protection
• Features an adjustable circuit breaker function controlled via an external switch
• Supports bidirectional current flow for versatile power distribution applications

Surge Suppression ICS Applications

• Automotive electronic systems
• Industrial power distribution networks
• Portable instrumentation equipment

Surge Suppression ICS Procurement Notes

Verify the specific suffix #WPBF against the manufacturer's latest documentation to confirm lead-free compliance status. Confirm that the DFN-10 package dimensions match the target PCB footprint requirements. Ensure the input voltage range remains within the specified 2.5 VDC to 60 VDC limits during operation.

Surge Suppression ICS Selection Notes

Select this component when bidirectional protection is required for high-voltage bus lines. Compare against the LTC4368IMS variant if a smaller MSOP-10 package is preferred but lower thermal performance is acceptable. Verify that the external switch interface meets the system's control logic requirements.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 series of ideal diode controllers and surge protectors. It complements other variants like the LTC4368HMS-1#WPBF which uses an MSOP-10 package. The series focuses on robust protection for sensitive electronics against transient voltage events and incorrect power connections.

Surge Suppression ICS Replacement Considerations

The LTC4368HDD-2#WPBF serves as a functional substitute within the same DFN-10 package family. Designers should verify pinout compatibility and threshold settings before substitution.
