Description and Introduction

IEEE 802.3af/at-Compliant, Powered Device Interface Controllers with Integrated 70W High-Power MOSFET The **MAX5982AETE+** is a Power over Ethernet (PoE) interface IC manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX5982AETE+  
- **Package:** 16-TQFN-EP (5x5)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 36V to 57V (compliant with IEEE 802.3af/at)  
- **Output Voltage:** Programmable (supports PD classification)  
- **Compliance:** IEEE 802.3af/at PoE standards  
- **Power Dissipation:** Up to 25.5W (supports Type 1 and Type 2 PDs)  

### **Descriptions:**  
- The **MAX5982AETE+** is a **PoE Powered Device (PD) controller** designed for use in network devices requiring power delivery over Ethernet cables.  
- It integrates detection, classification, and undervoltage lockout (UVLO) functions per IEEE 802.3af/at standards.  
- Provides a stable DC output voltage for PD applications, such as IP phones, wireless access points, and security cameras.  

### **Features:**  
- **IEEE 802.3af/at Compliant:** Supports detection, classification, and power delivery.  
- **Programmable Output Voltage:** Adjustable via external resistors.  
- **Integrated Power MOSFET:** Simplifies design and reduces external components.  
- **Inrush Current Limiting:** Protects against excessive current during startup.  
- **Thermal Shutdown:** Prevents overheating.  
- **Low Power Dissipation:** High efficiency for energy-sensitive applications.  
- **Small Footprint:** 16-TQFN package with exposed pad for thermal management.  

This information is based solely on the manufacturer's datasheet and technical documentation.
