LTC4380IMS-1#PBF

Overview

The LTC4380IMS-1#PBF is a board mount surge protector manufactured by Analog Devices Inc. It operates within a voltage range of 4 VDC to 72 VDC and features an MSOP-10 surface-mount package with dimensions of 3 mm x 3 mm x 0.86 mm. The device has a maximum operating temperature of +85°C and a minimum of -40°C. It is designed for applications in automotive, avionics, and industrial sectors.

Feature Summary

• Provides overvoltage protection by clamping the gate voltage of an external N-channel MOSFET during transient events such as load dump.
• Includes internal fixed gate clamp options selectable for 12V or 24V/28V systems to limit output voltage safely.
• Offers reverse input protection capability up to -60V through back-to-back MOSFET drive functionality.

Applications

• Automotive, Avionics, and Industrial Surge Protection
• Hot Swap / Hot Insert Applications
• High Side Switching for Battery Powered Systems

Procurement Notes

Verify current availability status directly with authorized distributors, as supply may be limited or subject to factory special orders. Confirm RoHS compliance details and specific packaging requirements prior to procurement. Ensure the component matches the exact suffix specifications required for the target application design.

Selection Notes

Select this component when low static current consumption is critical for battery-powered or always-on applications. Choose the IMS-1 variant specifically for systems requiring fixed internal gate clamp voltages suitable for standard 12V or 24V/28V architectures rather than adjustable clamp versions.

Part Context

This part belongs to the LTC4380 series of low quiescent current surge stoppers. It is distinct from other interface buffers like the LTC4313 or regulators like the LTC3025 found in related catalogs. The series focuses on protecting loads from high-voltage transients using external MOSFET control.

FAQ

Does the LTC4380IMS-1#PBF support hot swap operations?

Yes, the device supports hot swap and hot insert applications by controlling the external N-channel MOSFET to manage inrush currents and protect against surges.

What is the function of the ON pin on this device?

The ON pin acts as a comparator to monitor the input power for undervoltage conditions and can also serve as a shutdown input to reduce static current.
