Description and Introduction

Low-Voltage / Dual Hot-Swap Controllers/Power Sequencers The MAX5904USA is a power management IC manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX5904USA  
- **Type:** Hot-Swap Controller  
- **Operating Voltage Range:** 9V to 72V  
- **Maximum Continuous Current:** 1A  
- **Fault Protection:** Overcurrent, Undervoltage Lockout (UVLO), Thermal Shutdown  
- **Package:** 8-Pin SOIC  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX5904USA is a hot-swap controller designed to safely insert and remove circuit boards from a live backplane. It provides inrush current limiting, fault protection, and power management for high-voltage applications.

### **Features:**
- **Wide Input Voltage Range (9V to 72V)** – Suitable for telecom, industrial, and automotive applications.  
- **Programmable Current Limit** – Adjustable via an external sense resistor.  
- **Fast Overcurrent Protection** – Shuts down the load in case of excessive current.  
- **Undervoltage Lockout (UVLO)** – Ensures proper operation within the specified voltage range.  
- **Thermal Shutdown Protection** – Prevents damage due to overheating.  
- **Low Quiescent Current** – Reduces power consumption in standby mode.  

For detailed application notes and additional technical data, refer to the official Maxim Integrated datasheet.

Application Scenarios & Design Considerations

Low-Voltage / Dual Hot-Swap Controllers/Power Sequencers

Alternative Part Number

  • LTC4261IGN --: Hot swap controller with comparable function and pinout style, from a different series and vendor, suitable as a functional replacement.
  • TPS2491DGSR --: Positive high-voltage hot swap controller offering similar inrush and fault protection features, different naming and manufacturer.
  • ADM1075-1ARQZ --: Hot swap controller with current monitoring and protection, a distinct series that can serve as an alternative with design verification.
  • LTC4260CS8#PBF --: Hot swap controller in an SO-8 package with comparable supply voltage and current-monitoring features, suitable as a functional substitute.
  • ADM1075-1ARJZ --: Negative voltage hot swap controller with current sensing and fault handling, offering an alternative architecture for similar power-management applications.
