  - Integrated switching regulator controller  
- **Applications:** PoE midspan and endpoint power sourcing equipment (PSE)  

### **Descriptions:**  
The LTC4252CCMS-1#PBF is a PSE controller designed for managing power delivery in PoE systems. It provides detection, classification, and power control for connected PDs while ensuring compliance with IEEE 802.3af standards.  

### **Features:**  
- **Detection:** Identifies valid PDs using a signature resistor check.  
- **Classification:** Measures PD power requirements before enabling power.  
- **Inrush Current Control:** Limits startup current to prevent system disruptions.  
- **Power Management:** Supports external MOSFETs for power switching.  
- **Fault Protection:** Includes thermal shutdown and short-circuit protection.  

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