MAX5901AAETT+T

Hot Swap Controllers Overview

The MAX5901AAETT+T is a hot-swap voltage controller designed for -48V applications, operating within a supply range of -100V to -9V. It features adjustable current limiting and operates from -40°C to +85°C in a TDFN-6 package. The device provides overcurrent protection with a circuit-breaker function that limits inrush current during startup by gradually turning on an external N-channel MOSFET.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging into live backplanes without causing power-supply glitches
• Eliminates most external components, requiring only an external N-channel MOSFET
• Provides adjustable current limiting and circuit-breaker functionality for overcurrent protection

Hot Swap Controllers Applications

• -48V telecom line cards
• Circuit card hot-plugging into live backplanes
• Power-supply sequencing applications

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized channels as the part may be discontinued or subject to limited availability. Confirm RoHS compliance status and check for obsolescence notices (PCN) prior to procurement. Ensure the specific suffix matches design requirements, as packaging or revision changes may affect compatibility.

Hot Swap Controllers Selection Notes

Select this controller for -48V systems requiring simple hot-swap protection. It integrates current limiting and fault protection, reducing bill-of-materials complexity. Verify that the external MOSFET selection aligns with the controller's drive capabilities and thermal requirements for the specific load application.

Hot Swap Controllers Part Context

Part of the Simple Swapper family, which includes the MAX5900 and MAX5901 series. These controllers are optimized for negative voltage hot-swap applications, offering a compact solution compared to discrete implementations. The TDFN package supports surface-mount assembly for space-constrained designs.
