Description and Introduction

-48V Hot-Swap Controllers with External RSENSE The MAX5949AESA+ is a Power over Ethernet (PoE) interface controller manufactured by Maxim Integrated.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-SOIC (0.154", 3.90mm Width)  
- **Operating Temperature:** -40°C to +85°C  
- **Applications:** Power over Ethernet (PoE) systems  
- **Features:**  
  - IEEE 802.3af-compliant  
  - Integrated detection and classification  
  - Programmable inrush current control  
  - Under-voltage lockout (UVLO)  
  - Thermal shutdown protection  
  - Low-power dissipation  

### **Descriptions:**  
The MAX5949AESA+ is designed for use in Powered Device (PD) applications in PoE systems. It provides the necessary interface for PDs to receive power from Power Sourcing Equipment (PSE) while ensuring compliance with IEEE 802.3af standards.  

### **Features:**  
- **Detection & Classification:** Fully compliant with IEEE 802.3af standards.  
- **Inrush Current Control:** Limits inrush current to prevent system damage.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Thermal Protection:** Shuts down in case of excessive temperature.  
- **Low Power Dissipation:** Optimizes efficiency in PoE applications.  

This device is commonly used in network devices such as IP phones, wireless access points, and security cameras that require PoE functionality.
