LTC4227IUFD-2#TRPBF

Hot Swap Controllers Overview

The LTC4227IUFD-2#TRPBF is a hot swap voltage controller manufactured by Analog Devices Inc. It integrates two ideal diode controllers and one hot swap controller within a single QFN-20 package. The device operates with a supply voltage range of 2.9V to 18V and supports an operating temperature range from -40°C to 85°C. It features programmable current limit, fault timeout, and slew rate settings, along with auto-retry and UVLO capabilities.

Hot Swap Controllers Feature Summary

• Integrates dual ideal diode controllers and a single hot swap controller for redundant power path management
• Provides programmable control over current limiting, fault timeout duration, and inrush current slew rate
• Includes automatic retry functionality and undervoltage lockout (UVLO) protection mechanisms

Hot Swap Controllers Applications

• General purpose hot swap applications requiring redundant power supplies
• Power path management systems utilizing ideal diode configurations
• Inrush current control for sensitive electronic loads

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the manufacturer is Analog Devices Inc. and the part number matches exactly. Check RoHS compliance status through official documentation before integration into production designs.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring integrated ideal diode rectification alongside hot swap protection. The dual-channel ideal diode feature reduces external component count compared to discrete solutions. Ensure the 2.9V to 18V supply range aligns with system voltage requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC4227 series of hot swap voltage controllers. It shares functional similarities with the LTC4227IUFD-1#PBF and LTC4227IUFD-2#PBF variants, differing primarily in packaging format. The series is designed for efficient power distribution in telecommunications and industrial equipment.

Hot Swap Controllers Replacement Considerations

LTC4227IUFD-2#PBF serves as a tube-packaged alternative offering identical electrical performance. Verify pin compatibility and thermal characteristics when substituting between tape-and-reel and tube formats.
