  - Power good indicator  

### **Descriptions:**  
The MAX5948BESA+ is designed for use in IEEE 802.3af-compliant PoE applications. It provides a complete interface for a powered device (PD) to safely receive power from a Power Sourcing Equipment (PSE). The device includes detection, classification, and inrush current control, ensuring compliance with PoE standards.  

### **Features:**  
- **Detection & Classification:** Fully compliant with IEEE 802.3af standards.  
- **Inrush Current Limiting:** Prevents excessive current during startup.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Adjustable Output Voltage:** Allows flexibility in power delivery.  
- **Power Good Indicator:** Signals when the output is stable.  
- **Low Standby Current:** Optimizes power efficiency.  

This device is commonly used in network devices such as IP phones, wireless access points, and security cameras that require PoE power delivery.
