LTC4252CIMS-2#PBF

Hot Swap Controllers Overview

The LTC4252CIMS-2#PBF is a negative voltage Hot Swap controller from Analog Devices, designed for safe board insertion and removal from live backplanes. It operates within an input voltage range of -15 V to -500 V and features a single channel with programmable current limiting. The device draws 800 uA of operating supply current and supports auto-retry functionality. It includes fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). The component is housed in a 10-lead MSOP package and is rated for commercial temperature operation.

Hot Swap Controllers Feature Summary

• Enables safe hot swapping of boards into live negative voltage backplanes
• Provides programmable current limiting and fault management capabilities
• Integrates auto-retry logic for transient fault recovery

Hot Swap Controllers Applications

• Telecommunications equipment requiring negative bus power distribution
• Industrial control systems utilizing standard negative voltage backplanes
• Data communication infrastructure involving modular board insertion

Hot Swap Controllers Procurement Notes

Verify the specific suffix and tape-and-reel options against official Analog Devices documentation before ordering. Confirm that the negative voltage polarity requirements match your system architecture. Ensure compatibility with the MSOP-10 footprint during PCB layout. Check for any recent product change notices regarding pinout or electrical characteristics.

Hot Swap Controllers Selection Notes

Select this component when designing systems with negative voltage rails between -15 V and -500 V. It is suitable for applications requiring precise current limiting and automatic retry after fault conditions. Consider the MSOP-10 package size constraints and thermal performance. Verify that the commercial temperature range meets the operational environment requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC4252B/C series of negative voltage Hot Swap controllers. It shares functional similarities with other members of the family but differs in grade and specific parameter tolerances. The series is designed to protect downstream circuitry during unexpected power events and board swaps.

Hot Swap Controllers Replacement Considerations

LTC4252BCMS-2#PBF is a documented variant within the same family. Verify if the industrial grade or specific suffix differences impact the design requirements.
