Description and Introduction

IEEE802.3af Power Interface Switch For Power-Over-Ethernet (PoE) Powered Devices (PD's) The TPS2370DR is a Power over Ethernet (PoE) Powered Device (PD) interface controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 36V to 57V (PoE compliant)  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOIC-8  
- **Classification Current:** Supports IEEE 802.3af/at PD classification  
- **Detection Signature:** 25kΩ resistor  
- **Inrush Current Limit:** Programmable  
- **Power Good Output:** Indicates valid input voltage  
- **Under-Voltage Lockout (UVLO):** Adjustable  
- **Over-Current Protection (OCP):** Integrated  

### **Descriptions:**  
The TPS2370DR integrates the necessary functions for a PoE PD, including detection, classification, and inrush current limiting. It is designed to interface with a DC-DC converter to provide a stable power supply for connected devices.  

### **Features:**  
- IEEE 802.3af/at compliant  
- Supports both 2-event and 4-event classification  
- Programmable inrush current control  
- Thermal shutdown protection  
- Low standby power consumption  
- Integrated power MOSFET gate drive  

This information is based on TI's official datasheet for the TPS2370DR.
