MAX5902ACEUT+T

Hot Swap Controllers Overview

The MAX5902ACEUT+T is a hot-swap voltage controller designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of +9V to +72V and features adjustable undervoltage lockout. The device limits inrush current and provides circuit-breaker protection without requiring an external sense resistor. It drives an external p-channel MOSFET and includes thermal shutdown capabilities. The component draws less than 2mA of quiescent current and offers a power-good output rated for +72V.

Hot Swap Controllers Feature Summary

• Eliminates the need for an external sense resistor by integrating current limiting functions directly.
• Provides latching or automatic retry fault management to protect against overcurrent conditions.
• Includes thermal shutdown mechanisms to safeguard the external p-channel MOSFET from overheating.

Hot Swap Controllers Applications

• Network routers
• Servers
• RAID systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'ACEUT' against the manufacturer's official part numbering guide to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with the intended PCB footprint and soldering profile. Cross-reference the RoHS compliance status with the latest datasheet revision to meet environmental regulations. Confirm availability through authorized distributors as stock levels fluctuate.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring robust hot-swap protection for high-voltage rails up to 72V. It is suitable for applications needing precise inrush current control without additional sensing components. Consider the SOT-23 package size for space-constrained layouts. Evaluate the need for ON/OFF input sequencing if load power-supply control is required for the target application architecture.

Hot Swap Controllers Part Context

This component belongs to the Simple Swapper family of hot-swap controllers from Analog Devices/Maxim Integrated. The series focuses on simplifying power-up sequences and protecting backplane infrastructure. It complements other PMIC solutions by handling transient power events during card insertion, ensuring system stability in critical networking and industrial environments.

Hot Swap Controllers Replacement Considerations

The MAX5902NNEUT+T serves as a direct functional substitute within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution. Check for any differences in operating temperature ranges or package dimensions that might impact the existing design constraints.
