### **Descriptions:**  
The LTC4252-2IMS#PBF is a PoE controller designed for Power Sourcing Equipment (PSE) applications. It provides detection, classification, and power management for connected Powered Devices (PDs) in compliance with IEEE 802.3af standards.  

### **Features:**  
- **Autonomous Operation:** No software or external microcontroller required.  
- **Programmable Current Limit:** Adjustable via external resistor.  
- **Dual-Level Circuit Breaker:** Protects against overloads.  
- **Supports 2-Port PSE Applications:** Can control two independent PoE ports.  
- **Low Power Dissipation:** Reduces heat generation.  
- **Integrated Power MOSFETs:** Simplifies design and reduces external components.  
- **Supports DC Disconnect:** Ensures safe power removal.  

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