Description and Introduction

Positive High-Voltage, Hot-Swap Controller The MAX5932ESA is a power-over-Ethernet (PoE) interface controller manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Package:** 8-pin SOIC (ESA)  
- **Operating Voltage Range:** 36V to 57V (IEEE 802.3af compliant)  
- **Power Dissipation:** 725mW (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Detection Voltage Range:** 2.7V to 10V  
- **Classification Current:** Programmable per IEEE 802.3af  

### **Descriptions:**  
The MAX5932ESA is a fully integrated IEEE 802.3af-compliant PoE interface controller designed for Powered Devices (PDs). It provides detection, classification, and undervoltage lockout (UVLO) functions required for PoE applications.  

### **Features:**  
- IEEE 802.3af compliant  
- Integrated detection and classification  
- Programmable inrush current control  
- Thermal shutdown protection  
- Low standby current (<120µA)  
- Supports both 2-event and 4-event classification  
- Under-voltage lockout (UVLO) with hysteresis  

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

Application Scenarios & Design Considerations

Positive High-Voltage, Hot-Swap Controller

Alternative Part Number

  • LTC4357IMS8#PBF --: Ideal diode / hot swap controller in the same function class as the MAX5932, with comparable voltage and current ratings and an 8-pin MSOP package.
  • TPS2412D --: Hot swap power controller offering similar ORing and protection features, widely available and pin-function compatible for many MAX5932 designs.
  • LM5069MM-1/NOPB --: Hot swap controller with programmable current limit and fault protection, suitable as a functional replacement when layout adjustments are acceptable.
