Description and Introduction

IEEE 802.3-2005 PoE Interface and Isolated Converter and Controller 14-TSSOP -40 to 125 The TPS23753PWR is a Power over Ethernet (PoE) Powered Device (PD) interface controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 60V  
- **Operating Temperature Range:** -40°C to 125°C  
- **IEEE 802.3at (PoE+) Compliant**  
- **Integrated 100V, 0.4Ω Hot Swap MOSFET**  
- **Supports High-Power PD Applications (up to 25.5W)**  
- **Programmable Inrush Current Limit**  
- **Dual-Signature Detection for Redundancy**  
- **Classification Currents per IEEE 802.3at**  
- **Low-Power Sleep Mode for Non-PoE Operation**  
- **Package Type:** 16-pin TSSOP (PWR)  

### **Descriptions:**  
The TPS23753PWR integrates a PD interface and DC-DC converter controller for PoE applications. It supports IEEE 802.3at standards, enabling high-power delivery up to 25.5W. The device includes an internal hot-swap MOSFET, reducing external component count.  

### **Features:**  
- **Integrated PD and DC-DC Controller**  
- **Supports 4-Pair PoE (Alternative A & B)**  
- **Programmable Current Limit and Classification**  
- **Automatic MPS (Maintain Power Signature) Generation**  
- **Thermal Shutdown Protection**  
- **Low Quiescent Current in Sleep Mode**  

This device is commonly used in IP phones, wireless access points, and other PoE-powered systems.
