MAX5901ABEUT+

Hot Swap Controllers Overview

The MAX5901ABEUT+ 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 power-supply glitches. The device limits inrush current during startup and provides overcurrent protection with a circuit-breaker function. It operates within an extended temperature range of -40°C to +85°C and consumes a typical supply current of 500 µA. Packaged in a compact SOT-23-6 format, it requires only an external N-channel MOSFET for implementation.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging of circuit cards into live backplanes without causing power-supply glitches
• Limits inrush current by gradually turning on the external MOSFET during startup
• Provides overcurrent protection with a circuit-breaker function after startup completion

Hot Swap Controllers Applications

• Telecom line card power sequencing
• Industrial equipment hot-swap modules
• Server blade power management

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance and lead-free packaging specifications against the latest manufacturer datasheet. Ensure ordering suffixes match the required package type and temperature grade. Request batch traceability documentation for quality assurance purposes prior to final procurement approval.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring robust protection on negative voltage rails up to -100V. It eliminates the need for complex external components beyond the MOSFET. Consider thermal dissipation requirements when designing PCB layouts. Verify that the external MOSFET selection aligns with the device's current limiting capabilities and voltage ratings for optimal system performance.

Hot Swap Controllers Part Context

This component belongs to the Simple Swapper family of hot-swap controllers from Maxim Integrated. These devices are engineered to simplify power distribution systems by providing integrated protection features. The MAX5901 series specifically targets high-voltage negative rail applications common in telecommunications and industrial infrastructure environments.

Hot Swap Controllers Replacement Considerations

The MAX5900AAEUT+T serves as a functional substitute within the same product family. Both devices share identical electrical characteristics and pin configurations. Verify that the replacement part meets the specific temperature and package requirements of the original design.
