LT4250LCS8#PBF

Hot Swap Controllers Overview

The LT4250LCS8#PBF is a single-channel hot-swap controller manufactured by Analog Devices Inc., designed for negative voltage applications up to -48V. It utilizes an 8-pin SOIC package and supports surface-mount installation. This component integrates control circuitry for safe insertion and removal of live cards in telecommunications and industrial systems, managing inrush current and overvoltage protection without external sense resistors.

Hot Swap Controllers Feature Summary

• Integrates high-side N-channel MOSFET driver with built-in current limit and foldback control
• Provides undervoltage lockout and overvoltage protection for system bus integrity
• Supports controlled power-up sequencing via soft-start functionality

Hot Swap Controllers Applications

• Telecommunications backplane card insertion
• Industrial I/O module hot-plugging
• Negative voltage distribution networks

Hot Swap Controllers Procurement Notes

Verify the specific suffix CS8 against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with -48V negative supply architectures. Cross-reference datasheet revision dates to validate pinout and electrical characteristics before integration into final designs.

Hot Swap Controllers Selection Notes

Select this part for negative voltage hot-swap requirements where integrated control reduces external component count. Compare performance against LT4250H variants for temperature range differences. Confirm that the 8-SOIC package fits the target PCB footprint and thermal constraints.

Hot Swap Controllers Part Context

This device belongs to the LT4250 family of hot-swap controllers. It shares functional similarities with other members like LT4250LIS8 and LT4250HCN8 but differs in package style and operating temperature specifications. The family targets robust power management in harsh environments.

Hot Swap Controllers Replacement Considerations

LT4250LCS8#TRPBF offers identical functionality in tape-and-reel packaging. LT4250HCS8#PBF provides higher temperature range options. Verify pin compatibility and thermal performance when substituting.
