LTC4368IDD-1#WTRPBF

Surge Suppression ICS Overview

The LTC4368IDD-1#WTRPBF is a board mount surge protector manufactured by Analog Devices Inc. It functions as an undervoltage (UV), overvoltage (OV), and reverse protection controller with a bidirectional circuit breaker. The device operates within a voltage range of 2.5 V to 60 V and features a maximum supply current of 30 uA. It is housed in a 10-WFDFN package measuring 3 mm x 3 mm with a height of 0.75 mm. The component supports surface mount technology and operates between -40°C and +85°C.

Surge Suppression ICS Feature Summary

• Controls gate voltage of external back-to-back MOSFETs to isolate loads during faults
• Provides bidirectional overcurrent protection via integrated circuit breaker
• Allows adjustable UV and OV thresholds using external resistive dividers

Surge Suppression ICS Applications

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

Surge Suppression ICS Procurement Notes

Verify availability status directly with the manufacturer or authorized distributors, as supply may be restricted. Confirm that the specific suffix matches the required packaging format for production lines. Ensure compliance with RoHS directives and check for any regional shipping restrictions applicable to the destination address prior to finalizing orders.

Surge Suppression ICS Selection Notes

Select this component when high-voltage input protection up to 100V is required alongside precise UV/OV monitoring. The bidirectional circuit breaker capability distinguishes it from standard unidirectional protectors. Consider the DFN-10 package dimensions for PCB layout constraints and verify that the external MOSFET selection aligns with the controller's drive capabilities.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 series of power management ICs designed for robust system protection. It integrates control logic for external switches rather than containing internal power FETs. The series is engineered for automotive and industrial environments requiring reliable fault isolation against voltage spikes and reverse polarity events.

Surge Suppression ICS FAQ

How are the overvoltage and undervoltage protection levels determined?

The protection thresholds are adjusted externally using resistive voltage dividers connected to the OV and UV pins.

What type of external components does the LTC4368 control?

It controls the gate voltage of two back-to-back connected external N-channel MOSFETs to manage load connection.
