Description and Introduction

+48V, Single-Port Network Power Switch For Power-Over-LAN The MAX5922CEUI is a power management IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX5922CEUI  
- **Package:** 28-TSSOP (Thin Shrink Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 36V to 57V (typical for Power over Ethernet applications)  
- **Output Voltage:** Programmable (supports IEEE 802.3af/at standards)  
- **Maximum Output Current:** Up to 600mA (depends on configuration)  
- **Power Dissipation:** Internally limited for protection  
- **Compliance:** IEEE 802.3af/at PoE (Power over Ethernet) standards  

### **Descriptions:**
The MAX5922CEUI is a **Power over Ethernet (PoE) Powered Device (PD) interface controller**. It integrates detection, classification, and undervoltage lockout (UVLO) functions required for IEEE 802.3af/at compliance. It is designed to manage power delivery in PoE applications, ensuring safe and efficient power extraction from Ethernet cables.

### **Features:**
- **Complete PD Interface:** Includes detection, classification, and UVLO per IEEE 802.3af/at.  
- **Programmable Inrush Current Limit:** Prevents excessive current during startup.  
- **Integrated Power MOSFET:** Simplifies design and reduces external components.  
- **Thermal Protection:** Prevents overheating.  
- **Dual-Level Current Limit:** Enhances system safety.  
- **Supports Auxiliary Power:** Allows use of an auxiliary power source when available.  
- **Low-Power Mode:** Reduces power consumption when not active.  

This IC is commonly used in **IP phones, wireless access points, security cameras, and other PoE-powered devices**.
