MAX5900ACEUT-T

Hot Swap Controllers Overview

The MAX5900ACEUT-T is a hot-swap voltage controller designed for negative supply rails ranging from -9V to -100V. It enables safe insertion of circuit cards into live backplanes without causing power-supply glitches. The device operates with a single external n-channel MOSFET and features adjustable current limiting. It includes an integrated circuit-breaker function for overcurrent protection and disables this function during startup to manage inrush current by gradually turning on the MOSFET.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging of circuit cards into live backplanes without disrupting the power-supply rail
• Simplifies design by requiring only one external n-channel MOSFET for operation
• Provides adjustable inrush current limiting to control power-up sequences
• Integrates a circuit-breaker function for robust overcurrent protection

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe module insertion
• Industrial control systems with high-voltage negative bus architectures
• Server and storage backplanes supporting hot-swappable drives
• Networking infrastructure hardware requiring reliable power sequencing

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'ACEUT' against official Analog Devices documentation to confirm package type and temperature range. Confirm availability status as distribution channels may list limited stock or obsolete variants. Ensure the component matches the required negative voltage rating for your specific application before procurement.

Hot Swap Controllers Selection Notes

Select this controller when designing systems with negative power supplies between -9V and -100V. It is suitable for applications requiring minimal external components and precise control over inrush currents. Consider the TDFN/SOT23 package constraints and ensure the external MOSFET ratings align with the controller's capabilities.

Hot Swap Controllers Part Context

This component belongs to the MAX5900/MAX5901 family of Simple Swapper Hot-Swap Controllers. These devices are engineered to protect power buses during hot-insertion events. The family typically supports both positive and negative voltage ranges, with this specific part addressing the negative rail requirement common in telecom and industrial standards.

Hot Swap Controllers Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the MAX5900AAEUT+T or MAX5900ABETT+T. Verify that any replacement maintains compatibility with the -100V operating range and the specific pinout configuration.
