MAX5901NNETT+T

Hot Swap Controllers Overview

The MAX5901NNETT+T is a hot-swap voltage controller designed for safe insertion of circuit cards into live backplanes. It operates from -9V to -100V and requires only an external N-channel MOSFET. The device limits inrush current during startup and provides overcurrent protection via a circuit-breaker function that activates after the initial ramp-up period.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging into live backplanes without power-supply glitches
• Limits inrush current by gradually turning on the external MOSFET
• Provides overcurrent protection through a circuit-breaker function

Hot Swap Controllers Applications

• Telecom line card insertion
• Live backplane circuit card replacement
• Power supply sequencing protection

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be discontinued or subject to limited availability. Ensure the specific suffix matches your packaging requirements.

Hot Swap Controllers Selection Notes

Select this controller when operating within a -9V to -100V negative supply range. It is suitable for applications requiring minimal external components and robust inrush current limiting. Verify compatibility with the chosen external N-channel MOSFET for optimal performance.

Hot Swap Controllers Part Context

Part of the Simple Swapper family, which simplifies hot-swap design by integrating control logic. This series eliminates the need for complex discrete circuits, offering a compact solution for protecting power rails during module insertion in industrial and telecom systems.

Hot Swap Controllers Replacement Considerations

MAX5900AAEUT+T: Similar -100V operation but different package. MAX5903NNEUT+T: Positive voltage variant (9V-72V). Verify pinout and voltage polarity compatibility before substitution.
