Description and Introduction

Positive High Voltage Hot Swap / Inrush Current Controller with Power Limiting 10-VSSOP -40 to 125 The LM5069MM-2 is a high-voltage protection controller manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Input Voltage Range:** 9V to 100V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Pin VSSOP (MSOP)  
- **Overvoltage Protection (OVP):** Adjustable threshold  
- **Undervoltage Lockout (UVLO):** Adjustable threshold  
- **Reverse Polarity Protection:** Yes  
- **Current Limit Protection:** Adjustable  
- **Gate Drive Output:** For controlling an external N-channel MOSFET  
- **Fault Timer:** Adjustable for overload conditions  

### **Descriptions:**  
The LM5069MM-2 is designed to protect systems from high-voltage transients, reverse polarity, and overcurrent conditions. It integrates adjustable OVP, UVLO, and current limiting with an external MOSFET for robust power management.  

### **Features:**  
- Wide input voltage range (9V to 100V)  
- Adjustable OVP and UVLO thresholds  
- Reverse polarity protection with external MOSFET  
- Programmable fault timer for overload conditions  
- Low quiescent current in shutdown mode  
- Thermal shutdown protection  
- Robust gate drive for fast MOSFET switching  

This device is commonly used in industrial, automotive, and telecom applications requiring high-voltage protection.

Application Scenarios & Design Considerations

Positive High Voltage Hot Swap / Inrush Current Controller with Power Limiting 10-VSSOP -40 to 125

Alternative Part Number

  • TPS2491DGSR --: Positive high-voltage hot-swap controller with programmable current limit and fault timer, functionally similar to the LM5069 and available in a smaller VSSOP package.
  • MAX5902AAETT+T --: Hot-swap controller with inrush current limiting and circuit-breaker protection, suitable as a functional replacement in 12V/24V backplane applications.
  • LTC4261IGN#PBF --: Negative/positive hot-swap controller with current monitoring and adjustable fault timer, offering comparable protection features for high-side hot-swap designs.
  • LTC4260IGN --: Hot-swap controller with current monitoring and fault protection, suitable as a higher-integration substitute where board space allows.
