LTC4380IDD-3#PBF

Surge Suppression ICS Overview

The LTC4380IDD-3#PBF is a low quiescent current surge stopper manufactured by Analog Devices Inc. It protects loads from high voltage transients by clamping the gate voltage of an external N-channel MOSFET. The device features an adjustable gate clamp voltage suitable for systems up to 72V. It operates within a wide input voltage range of 4V to 72V and draws only 8µA of operating current. The component provides overcurrent protection with a fault timer based on MOSFET stress. It supports latch-off and restart options and includes reverse input protection capabilities.

Surge Suppression ICS Feature Summary

• Provides overvoltage protection by clamping external N-channel MOSFET gate voltage during transients
• Features adjustable gate clamp voltage for system voltages up to 72V
• Includes overcurrent protection with a fault timer proportional to MOSFET stress
• Supports reverse input protection via back-to-back MOSFET drive capability

Surge Suppression ICS Applications

• Automotive load dump protection
• Avionics surge suppression
• Industrial power supply protection
• Battery-powered system high-side switching

Surge Suppression ICS Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation risks. Confirm package type DFN-10 and RoHS compliance through official datasheets. Ensure ordering suffix matches required clamp voltage configuration. Cross-reference manufacturer part numbers to avoid counterfeit components. Check for product change notifications affecting specifications.

Surge Suppression ICS Selection Notes

Select this component when adjustable gate clamp voltage is required for systems exceeding standard 12V or 24V/28V fixed options. Choose for applications demanding ultra-low quiescent current in always-on or battery-powered designs. Consider for environments requiring robust reverse input protection without Schottky diode losses. Verify thermal performance requirements against MOSFET stress limits defined by the internal multiplier.

Surge Suppression ICS Part Context

The LTC4380 series comprises low quiescent current surge stoppers designed for protecting sensitive electronics from voltage spikes. The IDD-3 variant specifically denotes the adjustable gate clamp version, distinguishing it from fixed clamp models like the IDD-1 and IDD-2. This family is engineered for automotive, avionics, and industrial markets where reliability under transient conditions is critical.
