Description and Introduction

-48V Hot-Swap Controller with External RSENSE The MAX5920BESA is a power-over-Ethernet (PoE) interface IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX5920BESA  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 36V to 57V (compliant with IEEE 802.3af standard)  
- **Detection Voltage Range:** 2.7V to 10V  
- **Classification Current:** Programmable per IEEE 802.3af  
- **Power Dissipation:** Low quiescent current  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX5920BESA is a power sourcing equipment (PSE) controller designed for PoE applications. It provides detection, classification, and power management for powered devices (PDs) in compliance with the IEEE 802.3af standard. The IC ensures safe power delivery by monitoring the connection and preventing damage from incorrect PDs.

### **Features:**
- **IEEE 802.3af Compliant:** Supports detection and classification of PDs.  
- **Programmable Classification:** Adjustable classification current for power level identification.  
- **Integrated Power MOSFET:** Simplifies design by eliminating external switching components.  
- **Low Quiescent Current:** Optimized for energy efficiency.  
- **Overcurrent Protection:** Safeguards against excessive current draw.  
- **Thermal Shutdown:** Prevents overheating.  
- **Small Footprint:** 8-pin SOIC package for space-constrained applications.
