Description and Introduction

IEEE 802.3af PoE Powered Device Controllers 8-SOIC -40 to 85 The TPS2376DG4 is a Power over Ethernet (PoE) Powered Device (PD) interface and DC-DC controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 36V to 57V (PoE compliant)  
- **Output Voltage:** Adjustable via external components  
- **Maximum Output Current:** Depends on external MOSFET and inductor selection  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (DG4)  
- **Compliance:** IEEE 802.3af/at compliant  

### **Descriptions:**  
The TPS2376DG4 integrates a PD interface and a DC-DC controller for PoE applications. It supports detection, classification, and inrush current limiting as per IEEE 802.3af/at standards. The device enables efficient power conversion from PoE input to regulated DC output.  

### **Features:**  
- **Integrated PD Interface:** Supports IEEE 802.3af/at compliance  
- **Programmable Inrush Current Limit:** Prevents excessive current during startup  
- **Adjustable Output Voltage:** Configurable through feedback resistors  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Low-Power Sleep Mode:** Reduces power consumption when disabled  

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