Description and Introduction

Power over Ethernet IEEE 802.3af PD Interface with Integrated Switching Regulator The LTC4267IDHC#PBF is a Power over Ethernet (PoE) interface controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Linear Technology (Analog Devices)  
- **Package:** 16-Lead DFN (DHC)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Input Voltage Range:** Up to 57V  
- **Compliance:** IEEE 802.3af/at PoE Standards  
- **Features:**  
  - Integrated detection and classification  
  - Programmable inrush current control  
  - Supports high-power applications (up to 25.5W)  
  - Thermal shutdown protection  
  - Under-voltage lockout (UVLO)  

### **Descriptions:**  
The LTC4267IDHC#PBF is a robust PoE interface controller designed for Power Sourcing Equipment (PSE) applications. It provides accurate detection and classification of Powered Devices (PDs) while managing power delivery with programmable current limits.  

### **Features:**  
- **Detection:** Validates PD presence before power application  
- **Classification:** Determines PD power requirements  
- **Inrush Control:** Limits surge current during power-up  
- **Power Management:** Adjustable current limit and fault handling  
- **Protection:** Thermal shutdown and UVLO for safe operation  

This device is commonly used in network switches, routers, and other PoE-enabled infrastructure.  

(Note: For detailed electrical characteristics, refer to the official datasheet.)
