LT4250LIN8#PBF

Hot Swap Controllers Overview

The LT4250LIN8#PBF is a negative 48V hot swap controller designed for safe insertion and removal of circuit boards from live backplanes. It operates within an input voltage range of -80V to -18V and features a single channel with no internal switch, requiring an external N-channel MOSFET. The device supports through-hole mounting in an 8-DIP package. Key programmable protections include current limiting, overvoltage protection (OVP), undervoltage lockout (UVLO), and fault timeout. It functions reliably across an operating temperature range of -40°C to 85°C with a supply current of 1.6 mA.

Hot Swap Controllers Feature Summary

• Enables safe board insertion and extraction from energized backplanes by controlling an external N-channel pass transistor gate voltage.
• Integrates comprehensive protection mechanisms including programmable current limiting, overvoltage protection, undervoltage lockout, and fault timeout detection.
• Supports negative voltage applications up to -80V with a dedicated single-channel architecture for precise power management control.

Hot Swap Controllers Applications

• Telecommunications equipment requiring -48V power distribution
• Industrial control systems with live backplane architectures
• Data center infrastructure components needing safe module replacement

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'LIN8#PBF' corresponds to the 8-pin PDIP tube packaging variant. Confirm RoHS3 compliance status if required for your manufacturing process. Ensure the ordering quantity aligns with standard tube quantities rather than individual unit counts. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid confusion with similar LT4250 variants.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require robust hot swap capabilities for negative voltage rails. It is suitable for applications demanding high reliability during board maintenance without system shutdown. Consider the external MOSFET selection carefully as the controller manages only the gate drive. Evaluate the thermal performance requirements given the through-hole package constraints and ambient operating conditions.
