LTC4228CUFD-1#TRPBF

Hot Swap Controllers Overview

The LTC4228CUFD-1#TRPBF is a dual-channel hot swap voltage controller manufactured by Analog Devices Inc. It integrates two ideal diode controllers and hot swap control logic within a single QFN-24 package. The device supports independent channel operation for managing insertion and removal of live circuit boards. It features programmable current limit thresholds and soft-start timing to prevent inrush currents. The component operates with supply voltages typically ranging from 3V to 5.5V, suitable for standard backplane applications requiring precise power management and fault protection.

Hot Swap Controllers Feature Summary

• Integrates dual ideal diode controllers for efficient power path management
• Provides independent hot swap control for safe board insertion and removal
• Includes programmable current limiting and soft-start capabilities
• Offers comprehensive fault protection including overvoltage and thermal shutdown

Hot Swap Controllers Applications

• Server and storage backplane power distribution
• Telecommunications equipment hot swap modules
• Industrial control system expansion cards
• Network infrastructure board replacement systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the CUFD-1 designation matches the required temperature grade and package variant. Ensure compatibility with existing gate drive resistors and sense resistor values. Check for RoHS compliance documentation if required by regional regulations. Validate availability status as supply may be limited or subject to allocation.

Hot Swap Controllers Selection Notes

Select this component for designs requiring dual-channel power management in compact footprints. Consider the QFN-24 package for space-constrained PCB layouts. Evaluate the need for independent channel control versus shared regulation. Verify that the input voltage range aligns with the system bus requirements. Assess thermal performance based on expected load currents and ambient conditions.

Hot Swap Controllers Part Context

This part belongs to the LTC4228 family of hot swap controllers designed for high-reliability applications. It complements other Analog Devices power management solutions by providing integrated fault handling. The device is often used alongside voltage regulators and monitoring ICs in complex power architectures. Its design focuses on simplifying board-level power sequencing and protection mechanisms.

Hot Swap Controllers Replacement Considerations

Direct substitutes include the LTC4228CDHD-1#TRPBF for DFN-16 package variants. The LTC4228CUFD-1#PBF offers tube packaging instead of tape and reel. Cross-reference pinouts and electrical characteristics before substitution. Verify that alternative packages meet thermal and mechanical constraints.
