LT4250LIS8#PBF

Hot Swap Controllers Overview

The LT4250LIS8#PBF is a single-channel hot swap controller manufactured by Analog Devices Inc., designed for negative voltage applications up to -48V. It operates within a supply voltage range of 18V to 80V and features a current consumption of 1.6 mA. The device is housed in an 8-SOIC package with a standard operating temperature range of -40°C to +85°C. Key programmable characteristics include current limiting, fault timeout, overvoltage protection (OVP), undervoltage lockout (UVLO), and latch-on fault handling.

Hot Swap Controllers Feature Summary

• Provides integrated control for safe insertion and removal of live circuit boards in negative voltage systems.
• Features programmable current limiting and fault timeout mechanisms to protect against short circuits and overloads.
• Includes built-in undervoltage lockout and overvoltage protection for robust power management.

Hot Swap Controllers Applications

• Telecommunications equipment requiring -48V power distribution
• Industrial control systems utilizing hot swap capabilities
• Data center infrastructure managing negative voltage backplanes

Hot Swap Controllers Procurement Notes

Verify the specific suffix IS8 corresponds to the SOIC-8 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to final procurement decisions.

Hot Swap Controllers Selection Notes

Select this component for designs requiring precise control of inrush current and fault response in negative voltage environments. Ensure the system voltage remains within the 18V to 80V operational window. Consider the 8-SOIC package constraints for PCB layout and thermal management requirements during the design phase.

Hot Swap Controllers Part Context

This part belongs to the LT4250 family of hot swap controllers from Analog Devices. It serves as a specialized power management IC intended to facilitate the safe connection and disconnection of hardware modules without disrupting system operation or damaging components.

Hot Swap Controllers Replacement Considerations

LT4250HIS8#PBF offers similar functionality with a higher temperature rating. LT4250LCS8#PBF provides the same electrical specifications but utilizes a different package configuration.
