LT4254CGN#TRPBF

Hot Swap Controllers Overview

The LT4254CGN#TRPBF is a high-voltage Hot Swap controller designed for safe board insertion and removal from live backplanes. It features an internal driver for N-channel MOSFETs, supporting supply voltages between 10.8V and 36V. The device operates within a commercial temperature range of 0°C to 70°C with a typical supply current of 1.9 mA. Packaged in a 16-lead SSOP, it integrates programmable fault timeout, auto-retry, and overvoltage protection capabilities for robust power management.

Hot Swap Controllers Feature Summary

• Enables safe insertion and removal of boards from live backplanes using an internal driver for external N-channel MOSFETs
• Integrates programmable protection features including current limit, fault timeout, and overvoltage protection
• Supports wide input voltage range suitable for high-voltage positive hot swap applications

Hot Swap Controllers Applications

• Server and storage backplane systems requiring safe module insertion
• High-voltage positive hot swap controllers in industrial equipment
• Power management units needing integrated fault protection and retry logic

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. or its subsidiary Linear Technology. Ensure the component meets RoHS compliance requirements if specified by your project standards. Check for any product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component for applications requiring high-voltage hot swap capability up to 36V. It is suitable where integrated fault handling and auto-retry functions are necessary to maintain system availability. Consider the 16-SSOP package constraints for PCB layout. Verify that the external MOSFET selected can handle the expected load currents and voltage stresses defined by the controller's limits.

Hot Swap Controllers Part Context

This part belongs to the LT4254 family of hot swap controllers from Analog Devices. It is functionally similar to the LT4254CGN#PBF but differs in packaging format. The series is designed for positive voltage hot swap applications, providing a complete solution for protecting circuits during thermal cycling and fault conditions without requiring complex external logic.

Hot Swap Controllers Replacement Considerations

The LT4254CGN#PBF is a direct functional substitute with identical electrical specifications, differing only in tube versus tape-and-reel packaging. No other cross-model replacements are confirmed in the provided documentation.
