Description and Introduction

IEEE 802.3af/at-Compliant, Powered Device Interface Controllers with Integrated Power MOSFET The **MAX5969AETB+** is a power management IC manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX5969AETB+  
- **Package:** 10-WLP (Wafer-Level Package)  
- **Input Voltage Range:** 36V to 57V (with transient tolerance up to 100V)  
- **Output Voltage:** Programmable (supports IEEE 802.3af/at standards)  
- **Output Current:** Up to 600mA (for PoE applications)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The **MAX5969AETB+** is a **Power-over-Ethernet (PoE)** interface controller designed for **Powered Devices (PDs)**. It integrates a **PD detection and classification** circuit compliant with **IEEE 802.3af/at standards**, enabling safe power negotiation with Power Sourcing Equipment (PSE). It also includes an **inrush current limiter**, **thermal protection**, and **under-voltage lockout (UVLO)** for robust operation.  

### **Features:**  
- **IEEE 802.3af/at compliant** PD interface  
- **Integrated detection and classification**  
- **Programmable inrush current limit**  
- **Wide input voltage range (36V–57V)** with 100V transient tolerance  
- **Low-power dissipation** with high efficiency  
- **Thermal shutdown protection**  
- **Under-voltage lockout (UVLO)**  
- **Compact 10-WLP package** for space-constrained designs  

This IC is commonly used in **PoE-powered devices** such as **IP cameras, VoIP phones, wireless access points, and IoT devices**.  

(Note: All details are based on the manufacturer's datasheet and technical documentation.)
