Description and Introduction

-48V Hot-Swap Controllers with External RSENSE The MAX5948AESA is a power management IC (PMIC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX5948AESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Input Voltage Range:** 36V to 72V (withstand up to 100V)  
- **Output Voltage:** Adjustable or fixed (depends on configuration)  
- **Output Current:** Up to 400mA (for power supply applications)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:** Integrated power MOSFET, current limiting, thermal shutdown  

### **Descriptions:**  
The MAX5948AESA is a high-voltage power controller designed for Power over Ethernet (PoE) applications. It provides a complete solution for powered devices (PDs) by integrating detection, classification, and DC-DC converter control. It supports IEEE 802.3af/at standards and includes protection features like undervoltage lockout (UVLO), overcurrent protection, and thermal shutdown.  

### **Features:**  
- **IEEE 802.3af/at Compliant:** Supports PoE and PoE+ standards.  
- **Integrated DC-DC Controller:** Simplifies power supply design.  
- **Wide Input Voltage Range:** Operates from 36V to 72V.  
- **Detection and Classification:** Ensures compatibility with PoE switches.  
- **Protection Features:**  
  - Overcurrent protection  
  - Thermal shutdown  
  - Undervoltage lockout (UVLO)  
- **Compact Package:** 8-pin SOIC for space-constrained designs.  

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

(Note: Always verify datasheet details for exact application-specific parameters.)
