LTC4380CMS-3#TRPBF

Surge Suppression ICS Overview

The LTC4380CMS-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 voltage for flexible system integration. The device provides overcurrent protection via an internal multiplier that limits operating time based on MOSFET stress. It includes reverse input protection up to -60 V and supports latch-off or restart options. Packaged in a 10-lead MSOP, it offers low power consumption suitable for battery-powered applications.

Surge Suppression ICS Feature Summary

• Clamps external N-channel MOSFET gate voltage to limit output during overvoltage events
• Provides overcurrent protection with adjustable fault timer based on MOSFET stress
• Enables reverse input protection using back-to-back MOSFET configuration
• Features low quiescent current operation for always-on and battery-powered systems

Surge Suppression ICS Applications

• Automotive load dump protection
• Industrial and avionics surge suppression
• Hot-swap and live-insertion circuits
• Battery-powered system high-side switching

Surge Suppression ICS Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the CMS package designation matches the required MSOP-10 footprint for PCB layout compatibility. Ensure the adjustable clamp version aligns with the target system voltage requirements before procurement. Cross-reference the manufacturer datasheet for any recent product change notifications affecting this part number.

Surge Suppression ICS Selection Notes

Select this component when adjustable gate clamping is required for systems exceeding standard 12V or 24V/28V fixed thresholds. Choose the MSOP-10 package for space-constrained designs requiring surface-mount installation. Consider the low quiescent current specification for applications demanding minimal standby power consumption. Evaluate the latch-off versus restart functionality needs based on system recovery protocols after fault conditions.

Surge Suppression ICS Part Context

This component belongs to the LTC4380 family of low quiescent current surge stoppers manufactured by Analog Devices. The family includes variants with fixed or adjustable gate clamp voltages and different package options such as DFN and MSOP. These devices are engineered for robust protection against transient overvoltages and overcurrents in critical electronic systems.

Surge Suppression ICS Replacement Considerations

Direct substitutes include other LTC4380 variants with compatible pinouts and electrical characteristics. Verify that alternative parts support the same 4 V to 72 V operating range and adjustable clamp functionality. Ensure replacement components offer equivalent reverse input protection capabilities and package dimensions.
