LTC4224IMS-1#PBF

Hot Swap Controllers Overview

The LTC4224IMS-1#PBF is a hot-swap controller designed for high-side N-channel MOSFETs, featuring integrated current limit and soft-start capabilities. It supports input voltages from 3V to 60V and includes an adjustable current limit threshold via an external resistor. The device provides precise overvoltage protection with a trip point of 1.05 times the nominal supply voltage. It incorporates thermal shutdown and fault reporting through an open-drain flag output. The IC operates in a 10-lead MSOP package, ensuring compact integration into server and storage backplanes.

Hot Swap Controllers Feature Summary

• Integrated high-side N-channel MOSFET driver with programmable current limiting
• Precise overvoltage protection with automatic disconnect on fault detection
• Thermal shutdown protection to safeguard against overheating conditions

Hot Swap Controllers Applications

• Server and storage backplane power distribution
• Hot-swap modules for telecommunications equipment
• Industrial control systems requiring safe insertion and removal

Hot Swap Controllers Procurement Notes

Verify the specific suffix '-1' indicates the fixed overvoltage trip ratio. Confirm the 'IMS' package code matches the required 10-lead MSOP footprint. Ensure '#PBF' denotes lead-free and RoHS compliance status as per manufacturer specifications before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when a fixed overvoltage threshold at 1.05x Vsup is required. It is suitable for applications needing integrated current limiting without external sense amplifiers. Consider alternative models if adjustable overvoltage trip points or different package sizes are necessary for the design.

Hot Swap Controllers Part Context

This part belongs to Analog Devices' hot-swap controller family, specifically optimized for high-voltage applications up to 60V. It complements other LTC42xx series devices by offering a balance of performance and simplicity for standard hot-swap implementations in enterprise infrastructure.

Hot Swap Controllers Replacement Considerations

Direct replacements include other LTC4224 variants with different overvoltage ratios (e.g., LTC4224CMS-1) if the trip point needs adjustment. Verify pin compatibility and electrical parameters before substituting with generic hot-swap controllers.
