Description and Introduction

IEEE 802.3af PoE Powered Device Controllers The TPS2376PWR is a Power over Ethernet (PoE) Powered Device (PD) interface controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 0V to 57V  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 8-pin TSSOP (PWR)  
- **Compliance:** IEEE 802.3at (PoE+) standard  
- **Detection and Classification:** Supports PD detection and classification  
- **Inrush Current Limit:** Programmable  
- **Power Dissipation:** Low power dissipation in PD mode  
- **Under-Voltage Lockout (UVLO):** Adjustable  

### **Descriptions:**  
The TPS2376PWR integrates a PD interface and a DC-DC converter controller for PoE applications. It simplifies the design of IEEE 802.3at-compliant PDs, providing detection, classification, and inrush current control.  

### **Features:**  
- **Integrated PD Interface:** Compliant with IEEE 802.3at  
- **DC-DC Controller:** Supports flyback and forward converters  
- **Programmable Inrush Current Limit:** Ensures safe startup  
- **Thermal Protection:** Prevents overheating  
- **Adjustable UVLO:** Customizable for different applications  
- **Low Standby Power Consumption:** Optimized for efficiency  

This device is commonly used in PoE-powered applications such as IP phones, wireless access points, and security cameras.
