Description and Introduction

V(dd): 100V; negative voltage hot swap controller. For -48V power modules, cental office switching, distributed power systems, electronic circuit breaker, PBX systems, negative power supply control The LM5068MM-1 is a high-side protection controller manufactured by National Semiconductor (NSC). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** High-Side Protection Controller  
- **Package:** 10-Pin VSSOP (MM)  
- **Operating Voltage Range:** 4.5V to 80V  
- **Maximum Input Voltage (Absolute):** 100V  
- **Quiescent Current:** 150µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Gate Drive Output:** 5V (typical)  
- **Under-Voltage Lockout (UVLO):** Adjustable  
- **Over-Voltage Protection (OVP):** Adjustable  
- **Current Limit Protection:** Adjustable  

### **Descriptions:**
The LM5068MM-1 is designed to protect downstream circuitry from overvoltage, undervoltage, and overcurrent conditions in high-side power distribution applications. It integrates precision monitoring and control functions to ensure safe operation in industrial, automotive, and telecom systems.

### **Features:**
- **Adjustable Overvoltage Protection (OVP):** Prevents damage from excessive input voltage.  
- **Adjustable Undervoltage Lockout (UVLO):** Ensures proper operation within safe voltage limits.  
- **Programmable Current Limit:** Protects against excessive current draw.  
- **Fast Response Time:** Quickly reacts to fault conditions.  
- **Low Quiescent Current:** Minimizes power loss in standby mode.  
- **Wide Operating Voltage Range:** Suitable for 4.5V to 80V applications.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Gate Drive Output:** Controls an external N-channel MOSFET for power switching.
