LTC4380HDD-3#TRPBF

Surge Suppression ICS Overview

The LTC4380HDD-3#TRPBF is a low quiescent current surge stopper designed to protect loads from high voltage transients. It operates within a voltage range of 4 V to 72 V and features an adjustable gate clamp for flexible system integration. The device incorporates internal overcurrent protection that limits operating time during stress events. It utilizes an external N-channel MOSFET to eliminate the voltage drop associated with Schottky diode solutions, offering reverse input protection capabilities.

Surge Suppression ICS Feature Summary

• Provides overvoltage protection by clamping the gate voltage of an external N-channel MOSFET to limit output voltage during transient events such as automotive load dump.
• Integrates internal overcurrent protection using a multiplier that generates a current proportional to VDS and ID to limit MOSFET stress duration.
• Enables reverse input protection by driving back-to-back MOSFETs, thereby eliminating the forward voltage drop and power dissipation typical of Schottky diode configurations.

Surge Suppression ICS Applications

• Automotive systems requiring robust protection against high voltage transients
• Avionics circuits needing reliable surge suppression
• Industrial equipment demanding durable power input protection

Surge Suppression ICS Procurement Notes

Verify the specific package type and marking codes on the physical component to ensure alignment with the DFN-10 specification.
