Description and Introduction

IEEE 802.3af-Compliant Power-Over-Ethernet Interface/PWM Controller for Power Devices The MAX5941ACSE is a Power over Ethernet (PoE) interface controller manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Package:** 16-pin narrow SOIC (CSE)  
- **Operating Voltage Range:** 36V to 57V (IEEE 802.3af compliant)  
- **Detection Voltage:** 2.7V to 10V  
- **Classification Current:** Programmable (IEEE 802.3af compliant)  
- **Power Dissipation:** 1.5W (max)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX5941ACSE is designed for use in Powered Devices (PD) in PoE systems. It integrates detection, classification, and undervoltage lockout (UVLO) functions to comply with IEEE 802.3af standards. It provides a regulated output for PD applications while ensuring safe power-up and operation.  

### **Features:**  
- IEEE 802.3af compliant  
- Integrated detection and classification  
- Programmable inrush current control  
- Thermal shutdown protection  
- Under-voltage lockout (UVLO)  
- Supports both 2-event and 4-event classification  
- Low-power dissipation
