MAX5902LAEUT

Hot Swap Controllers Overview

The MAX5902LAEUT+T is a hot-swap voltage controller from the Simple Swapper series, designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of 9V to 72V and features a single channel in an SOT-23-6 surface-mount package. The device limits inrush current during startup and provides adjustable overcurrent protection with thermal limiting and fault timeout capabilities. It functions without an internal switch, requiring an external P-channel MOSFET, and maintains a low supply current of 1mA across an operating temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Eliminates power-supply glitches during hot-plugging by controlling inrush current
• Provides adjustable circuit-breaker functionality for overcurrent protection
• Integrates thermal limiting and fault timeout features for robust system safety

Hot Swap Controllers Applications

• Network equipment backplane power distribution
• Industrial control system card insertion
• Telecommunications infrastructure power modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'LA' against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the ordering number with Analog Devices documentation to validate the package type and tape-and-reel specifications before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring simple, component-efficient hot-swap protection for voltages up to 72V. It is suitable for applications where minimizing external bill-of-materials is critical, as it only requires an external MOSFET. Consider the SOT-23-6 footprint constraints and the need for external gate drive components when evaluating board space and design complexity.

Hot Swap Controllers Part Context

This component belongs to the MAX5902 family of hot-swap controllers manufactured by Analog Devices Inc./Maxim Integrated. The family is part of the Simple Swapper line, which focuses on simplifying hot-plug designs by reducing external component counts. These devices are widely used in industrial and telecommunications sectors for reliable power management during module insertion.
