Description and Introduction

Low-Voltage, Dual Hot-Swap Controllers with Independent On/Off Control The MAX5956AEEE is a power-over-Ethernet (PoE) interface controller manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated (Analog Devices)  

### **Part Number:**  
MAX5956AEEE  

### **Description:**  
The MAX5956AEEE is a PoE interface controller designed for use in Powered Devices (PDs) in IEEE 802.3af-compliant PoE systems. It integrates detection, classification, and undervoltage lockout (UVLO) functions, along with a switching regulator controller for efficient power conversion.  

### **Key Features:**  
- **Compliance:** IEEE 802.3af compliant  
- **Detection & Classification:** Supports PD detection and power classification  
- **Input Voltage Range:** Operates from 36V to 57V (nominal PoE input range)  
- **Integrated Power MOSFET:** Includes an internal N-channel MOSFET for DC-DC conversion  
- **Switching Regulator Controller:** Supports flyback or buck converter topologies  
- **Programmable UVLO:** Adjustable undervoltage lockout threshold  
- **Thermal Protection:** Built-in thermal shutdown  
- **Package:** 16-pin QSOP (Exposed Pad)  

### **Applications:**  
- VoIP phones  
- Wireless access points  
- IP cameras  
- Other IEEE 802.3af-compliant PDs

- **Operating Temperature Range:** -40°C to +85°C  
- **Integrated Features:**  
  - Detection and classification for Powered Devices (PD)  
  - Inrush current control  
  - Programmable current limit  

### **Descriptions:**  
The MAX5956AEEE is a Power over Ethernet (PoE) interface controller designed for IEEE 802.3af/at compliant Powered Devices (PDs). It provides a complete solution for PDs requiring power from PoE-enabled switches or midspan injectors. The device integrates detection, classification, and a robust power MOSFET for efficient power management.  

### **Features:**  
- **IEEE 802.3af/at Compliance:** Supports both standards for PoE power delivery.  
- **Detection & Classification:** Ensures compatibility with PoE power sources.  
- **Inrush Current Limiting:** Prevents excessive current during startup.  
- **Programmable Current Limit:** Adjustable for different PD requirements.  
- **Thermal Protection:** Prevents overheating.  
- **Wide Input Voltage Range:** Operates from 36V to 57V.  
- **Low Power Dissipation:** Optimized for efficiency.  
- **Compact Package:** 16-QSOP with exposed pad for thermal management.
