LTC4252-1IMS#TRPBF

Hot Swap Controllers Overview

The LTC4252-1IMS#TRPBF is a negative voltage hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 3V to 36V and features an adjustable current limit with constant current regulation. The device includes programmable soft-start, power limiting, and fault protection mechanisms such as overvoltage, undervoltage, and thermal shutdown. It is housed in a 10-lead MSOP package and supports surface-mount installation.

Hot Swap Controllers Feature Summary

• Provides precise control during insertion and removal of live circuit boards to prevent system damage.
• Integrates adjustable current limiting and constant current regulation for controlled power ramp-up.
• Includes comprehensive fault protection against overvoltage, undervoltage, and excessive temperature conditions.

Hot Swap Controllers Applications

• Negative voltage bus hot swapping in telecommunications infrastructure
• Controlled insertion and removal of peripheral cards in industrial systems
• Power distribution management in server backplanes

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the IMS designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure compatibility with negative voltage architectures, as this controller is designed specifically for negative rail applications rather than positive rails.

Hot Swap Controllers Selection Notes

Select this component for designs requiring robust protection on negative voltage buses where board replacement must occur without powering down the entire system. Consider the MSOP-10 footprint constraints and the need for external programming resistors to set current limits and delay times according to specific load requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC4252 family of hot swap controllers, which are engineered for managing power delivery during dynamic connection events. The series offers various pin counts and packages to suit different channel densities and thermal requirements within power management integrated circuits.

Hot Swap Controllers Replacement Considerations

Consult official substitution guides for equivalent negative voltage hot swap controllers from Analog Devices or other manufacturers. Verify pinout compatibility and electrical parameter alignment before replacing the original component in existing designs.
