Description and Introduction

IEEE 802.3af/at-Compliant, Powered Device Interface Controllers with Integrated Power MOSFET The **MAX5981AETE+** is a Power over Ethernet (PoE) interface IC manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** MAXIM (Analog Devices)  
- **Part Number:** MAX5981AETE+  
- **Package:** 16-TQFN-EP (5x5)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 36V to 57V (IEEE 802.3af/at compliant)  
- **Output Voltage:** Adjustable (supports PD classification)  
- **Power Dissipation:** Up to 25.5W (supports IEEE 802.3at Type 1 & Type 2)  
- **Compliance:** IEEE 802.3af/at PoE standards  

### **Descriptions:**  
The MAX5981AETE+ is a **PoE Powered Device (PD) interface controller** designed for IEEE 802.3af/at-compliant applications. It integrates detection, classification, and undervoltage lockout (UVLO) functions, enabling safe and efficient power delivery over Ethernet cables.  

### **Features:**  
- **Integrated PD Interface:** Supports detection, classification, and inrush current limiting.  
- **Programmable Classification:** Configurable for different power levels (Class 0 to 4).  
- **Wide Input Voltage Range:** 36V to 57V for IEEE 802.3af/at compliance.  
- **Low Power Dissipation:** Optimized for high efficiency.  
- **Thermal Protection:** Prevents overheating.  
- **Small Footprint:** 16-pin TQFN-EP package for space-constrained designs.
