MAX5901LCEUT+T

Hot Swap Controllers Overview

The MAX5901LCEUT+T is a hot-swap voltage controller designed for -48V applications, operating within a supply voltage range of -100V to -9V. It features adjustable current limiting and includes fault timeout and latch-up protection mechanisms. The device operates from -40°C to +85°C and consumes 500 µA of quiescent current. Packaged in a SOT-23-6 surface-mount format, it supports single-channel control without an internal switch.

Hot Swap Controllers Feature Summary

• Provides circuit-breaker functionality for overcurrent protection during hot-plugging operations
• Eliminates external components except for the required n-channel MOSFET
• Includes programmable undervoltage lockout (UVLO) capabilities

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 Analog Devices channels due to limited availability status. Confirm package integrity upon receipt as the device utilizes small outline packaging. Ensure compliance with RoHS3 specifications before integration. Check for obsolescence notices as the part may be discontinued or subject to production changes.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring safe insertion of circuit cards into active backplanes without power rail glitches. It is suitable for negative supply architectures ranging from -9V to -100V. Consider the SOT-23-6 footprint constraints and the necessity of an external N-channel MOSFET for implementation.

Hot Swap Controllers Part Context

This component belongs to the Simple Swapper family of hot-swap controllers manufactured by Maxim Integrated, now part of Analog Devices. These devices are engineered to simplify power management by integrating control logic that manages inrush current and provides robust protection against short circuits and overloads in high-voltage DC environments.
