LTC4380CMS-4#TRPBF

Surge Suppression ICS Overview

The LTC4380CMS-4#TRPBF 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, limiting output voltage during overvoltage events like automotive load dump. The device features a fixed gate clamp voltage selectable for 12V systems and operates within a wide input voltage range of 4 VDC to 72 VDC. It provides overcurrent protection with adjustable fault timers and reverse input protection via back-to-back MOSFETs. The component operates at a low 8 µA quiescent current and is housed in a 10-pin MSOP package.

Surge Suppression ICS Feature Summary

• Clamps external N-channel MOSFET gate voltage to limit output during overvoltage events
• Provides overcurrent protection with internal multiplier-based fault timer
• Enables reverse input protection using back-to-back MOSFET configuration
• Maintains low static current suitable for always-on and battery-powered applications

Surge Suppression ICS Applications

• Automotive load dump protection
• Industrial system surge suppression
• Avionics power line protection
• Battery-powered equipment input protection

Surge Suppression ICS Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and clamp voltage selection. Ensure the ordering part number matches the required package type and temperature rating. Confirm availability status through authorized distributors as supply may be restricted. Validate RoHS compliance details directly from the manufacturer's datasheet before procurement.

Surge Suppression ICS Selection Notes

Select this component when fixed 12V system clamp voltage is required rather than adjustable options. Consider the MSOP package dimensions for PCB layout constraints. Evaluate the 8 µA operating current against system standby requirements. Compare against other series members if different voltage ratings or latch-off behaviors are needed for the specific application design.

Surge Suppression ICS Part Context

This part belongs to the LTC4380 family of low quiescent current surge stoppers designed for protecting sensitive electronics from transient voltage spikes. The family includes variants with fixed or adjustable clamp voltages and different packaging options such as DFN and MSOP. These devices are engineered for high-reliability environments requiring robust overvoltage and overcurrent management capabilities.

Surge Suppression ICS Replacement Considerations

Check Analog Devices datasheets for compatible substitutes like LTC4380IMS-4#TRPBF or LTC4380IDD-2#TRPBF based on package and clamp voltage requirements. Verify that any replacement maintains the same 4 VDC to 72 VDC operating range and 8 µA quiescent current specifications.
