MAX5900LBEUT+T

Hot Swap Controllers Overview

The MAX5900LBEUT+T is a hot-swap voltage controller designed for -100V systems, operating within a supply range of -9V to -100V. It utilizes a 6-pin TDFN package and draws 500µA of quiescent current. The device supports adjustable current limiting and functions across an industrial temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging into live backplanes without causing power-supply glitches
• Limits inrush current during startup by gradually turning on the external MOSFET
• Provides circuit-breaker overcurrent protection with disabled breaker function during initial ramp-up

Hot Swap Controllers Applications

• -48V telecom line cards
• Industrial equipment requiring hot-swap capability
• Telecom infrastructure power distribution

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized channels as availability may be restricted. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements before soldering. Validate datasheet revisions against manufacturing dates.

Hot Swap Controllers Selection Notes

Select this controller for single-channel applications requiring robust protection in high-voltage negative rail environments. The integrated control logic minimizes external component count compared to discrete solutions. Verify that the external N-channel MOSFET ratings align with the system's peak current and voltage specifications.

Hot Swap Controllers Part Context

This component belongs to the Simple Swapper family of hot-swap controllers from Maxim Integrated. It shares functional similarities with the MAX5901 but is optimized for specific voltage ranges. The series focuses on simplifying board design by integrating control loops typically found in complex protection circuits.
