LTC4252BIMS-1#TRPBF

Hot Swap Controllers Overview

The LTC4252BIMS-1#TRPBF is a negative voltage hot swap controller manufactured by Analog Devices Inc. Designed for -48V systems, it manages power insertion into backplanes while preventing inrush current and overvoltage conditions. The device operates within a supply voltage range of -72V to -36V and features a low operating supply current of 800 µA. It is housed in an MSOP-10 surface-mount package and supports programmable fault timeouts, overvoltage protection, and undervoltage lockout. This component ensures reliable system availability during maintenance or board replacement.

Hot Swap Controllers Feature Summary

• Integrated control for negative voltage hot swap applications
• Programmable fault timeout and overvoltage protection mechanisms
• Low quiescent current operation for energy efficiency

Hot Swap Controllers Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against official Analog Devices documentation before procurement. Confirm that the component meets all required environmental and safety standards for your specific deployment environment. Ensure compatibility with existing -48V bus architectures and thermal management requirements.

Hot Swap Controllers Selection Notes

Select this controller for designs requiring precise management of negative voltage hot swap events. It is suitable for applications needing robust protection against inrush currents and short circuits without internal switches. Consider the MSOP-10 package constraints and verify that the external MOSFET selection aligns with the controller's drive capabilities and thermal performance targets.

Hot Swap Controllers Part Context

This part belongs to the LTC4252B series of negative voltage hot swap controllers from Analog Devices. It is engineered for high-power applications where system availability is critical. The series provides comprehensive protection features including energy monitoring and programmable limits, distinguishing it from simpler fuse-based solutions.

Hot Swap Controllers Replacement Considerations

Direct substitutes include other parts within the LTC4252 family, such as the LTC4252BCMS-1#PBF or LTC4252BIS6-1#TRMPBF, depending on the required package type and reel specifications. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
