LTC4225IGN-2#TRPBF

Hot Swap Controllers Overview

The LTC4225IGN-2#TRPBF is a dual-channel hot swap voltage controller manufactured by Analog Devices Inc. It integrates two ideal diode controllers and hot swap management circuits within a single SSOP-24 package. The device supports an input voltage range of 3V to 36V with a maximum continuous current of 10A per channel. Key electrical parameters include a quiescent current of 2.8mA, adjustable current limit thresholds, and programmable soft-start timing. It features precise overvoltage protection and power good signaling for reliable system insertion.

Hot Swap Controllers Feature Summary

• Integrates dual ideal diode controllers for reverse polarity protection and load sharing
• Provides active current limiting and thermal foldback for safe hot insertion
• Includes programmable soft-start to manage inrush currents during power-up

Hot Swap Controllers Applications

• Advanced Mezzanine Card (AMC) backplane power distribution
• Industrial control system board insertion management
• Telecommunications equipment power supply redundancy

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the part number matches the exact temperature grade and package variant required for your design. Cross-reference the datasheet revision date to confirm compliance with current RoHS standards and material declarations before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when dual-channel power path management is required on a single PCB footprint. It is suitable for applications needing independent current limiting and ideal diode functionality without external MOSFETs. Consider the SSOP-24 package constraints and thermal dissipation requirements relative to the expected load currents and ambient operating temperatures.

Hot Swap Controllers Part Context

This part belongs to the LTC4225 series of hot swap controllers designed for high-reliability systems. It complements other Analog Devices power management solutions by providing integrated protection and sequencing capabilities. The series is commonly used in modular electronics where board replacement must occur without disrupting system operation or damaging connected components.
