LTC4226CMS-2#TRPBF

Hot Swap Controllers Overview

The LTC4226CMS-2#TRPBF is a dual-channel hot swap controller designed for positive high-voltage applications. It operates within a supply voltage range of 4.5V to 44V and utilizes external N-channel MOSFETs. The device features a typical circuit breaker threshold voltage of 50mV and a maximum supply current of 2mA. It supports both auto-retry and latched-off fault management modes, with an auto-retry delay of 0.5 seconds. The component is housed in a 16-pin MSOP package and functions within a commercial temperature range of 0°C to 70°C.

Hot Swap Controllers Feature Summary

• Enables safe board insertion into live backplanes by controlling power-up sequencing.
• Provides selectable current limiting and dual-rate timer capabilities to accommodate load surges.
• Offers fast response times to limit peak fault currents during overcurrent events.

Hot Swap Controllers Applications

• Hot swap controllers for server blade insertion
• Backplane power distribution systems
• High-voltage peripheral card protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms the tape and reel packaging format required for automated assembly processes. Confirm that the commercial temperature grade (0°C to 70°C) aligns with the operational environment requirements. Ensure compatibility with external N-channel FET selection based on the specified 44V maximum operating voltage and current threshold parameters.

Hot Swap Controllers Selection Notes

Select this component when dual-channel independent control is required for positive high-voltage loads up to 44V. It is suitable for designs needing precise current limiting with external sense resistors and configurable fault handling via auto-retry or latch-off mechanisms. Consider the 16-pin MSOP package constraints for PCB layout and thermal management relative to the external MOSFET placement.

Hot Swap Controllers Part Context

This part belongs to the LTC4226 family of dual hot swap controllers from Analog Devices. It shares core functionality with variants like the LTC4226CMS-2#PBF, differing primarily in packaging type. The series is engineered for robust power management in industrial and communication equipment where live insertion safety is critical.

Hot Swap Controllers Replacement Considerations

The LTC4226CMS-2#PBF serves as a direct functional substitute with identical electrical characteristics, differing only in tube packaging instead of tape and reel. Verify pinout compatibility and ensure the alternative packaging meets the specific manufacturing assembly requirements.
