Description and Introduction

1 V to 13.2 V, n-channel hot-swap controller require no sense resistor The MAX5925DEUB is a power-over-Ethernet (PoE) interface controller 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 (now Analog Devices)  
- **Part Number:** MAX5925DEUB  
- **Package:** 10-µMAX® (3mm x 5mm)  
- **Operating Voltage Range:** 36V to 57V (IEEE 802.3af compliant)  
- **Detection Voltage Range:** 2.7V to 10V  
- **Classification Current:** Programmable per IEEE 802.3af  
- **Power Dissipation:** Low power dissipation in PD (Powered Device) mode  
- **Operating Temperature Range:** -40°C to +85°C  

### **Description:**  
The MAX5925DEUB is a PoE interface controller designed for use in Powered Devices (PDs) that comply with the IEEE 802.3af standard. It integrates detection, classification, and undervoltage lockout (UVLO) functions required for PoE applications. The device ensures safe power delivery to PDs while providing thermal and current protection.

### **Features:**  
- **IEEE 802.3af Compliant:** Supports detection, classification, and power delivery.  
- **Integrated 100V Power MOSFET:** Simplifies external circuitry.  
- **Programmable Classification:** Allows power negotiation with PSE (Power Sourcing Equipment).  
- **Thermal Protection:** Prevents overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Low Power Consumption:** Optimized for efficiency in PD applications.  
- **Compact Package:** 10-µMAX form factor for space-constrained designs.
