LTC4252BIMS-1#PBF

Hot Swap Controllers Overview

The LTC4252BIMS-1#PBF is a negative voltage hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of -15 V to -500 V and features a quiescent current of 800 uA. The device is housed in an MSOP-8 surface-mount package and supports operation across a temperature range of -40°C to +85°C. Designed for power distribution applications, it manages controlled insertion into live backplanes while protecting against overvoltage, undervoltage, and short circuit conditions.

Hot Swap Controllers Feature Summary

• Enables safe insertion and removal of cards from live backplanes by controlling the rate of voltage rise on output capacitors.
• Provides precise current limiting with programmable thresholds to protect downstream circuits during fault conditions.
• Integrates comprehensive fault protection including overvoltage, undervoltage lockout, and thermal shutdown mechanisms.

Hot Swap Controllers Applications

• Telecommunications equipment requiring -48V or -60V power distribution
• Industrial control systems utilizing negative rail power architectures
• Network infrastructure hardware needing protected card insertion

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Validate pin compatibility with target PCB footprint design specifications.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring negative voltage hot swap management. Verify input voltage ranges align with system power rails. Consider package constraints when designing PCB layouts. Evaluate current limit settings against load requirements to ensure adequate protection margins without nuisance tripping.

Hot Swap Controllers Part Context

This component belongs to the LTC4252B series of hot swap controllers designed for negative voltage systems. It complements other power management ICs in Analog Devices' portfolio by providing specialized protection for high-voltage negative rail applications commonly found in telecom and industrial sectors.

Hot Swap Controllers Replacement Considerations

LTC4252BCMS-1#PBF serves as a pin-compatible alternative featuring an MSOP-10 package instead of MSOP-8. Verify package dimensions and pinout compatibility before substitution. Both devices share similar electrical characteristics and functional capabilities for negative voltage hot swap control.
