MAX5922BEUI+

Overview

The MAX5922BEUI+ is a single-port network power switch designed for +48V applications, operating within a supply voltage range of 32 V to 60 V. It functions as a hot-swap controller with an internal switch capable of handling up to 15.4 W of power. The device features adjustable current limiting and operates at a quiescent current of 1 mA. It supports a wide temperature range from -40°C to +85°C and is housed in a 28-TSSOP surface-mount package.

Feature Summary

• Integrates a high-voltage power switch with adjustable current limiting for safe insertion into live networks
• Provides disabled detection and collision avoidance mechanisms to protect downstream components
• Includes thermal shutdown protection to ensure reliability under fault conditions

Applications

• Remote peripherals in industrial control systems
• Network cameras requiring Power over Ethernet (PoE)
• Data access equipment utilizing single-port network power switches

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm the specific suffix matches the required temperature grade and packaging format. Check current availability status as supply constraints may affect lead times. Ensure compliance with RoHS directives if applicable to your manufacturing requirements.

Selection Notes
