Description and Introduction

+48V, Single-Port Network Power Switch For Power-Over-LAN The MAX5922BEUI is a power-over-Ethernet (PoE) interface controller manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX5922BEUI  
- **Package:** 28-TSSOP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 3V to 5.5V  
- **Compliance:** IEEE 802.3af compliant  
- **Power Classification:** Supports detection and classification for powered devices (PDs)  
- **Power Dissipation:** Low power dissipation  

### **Descriptions:**
The MAX5922BEUI is a PoE interface controller designed for use in powered devices (PDs) that comply with the IEEE 802.3af standard. It integrates detection, classification, and undervoltage lockout (UVLO) functions required for PoE applications. The device ensures safe power delivery to PDs while minimizing power dissipation.

### **Features:**
- **IEEE 802.3af Compliance:** Fully compliant with PoE standards.  
- **Integrated Detection & Classification:** Supports PD detection and power classification.  
- **Undervoltage Lockout (UVLO):** Ensures proper power-up sequencing.  
- **Low Power Dissipation:** Optimized for efficiency.  
- **Wide Input Voltage Range:** Operates from 3V to 5.5V.  
- **Thermal Protection:** Includes thermal shutdown for safety.  
- **Small Form Factor:** 28-pin TSSOP package for space-constrained applications.
