Description and Introduction

Negative Voltage Hot Swap Controller The LT1640LIS8#TRPBF is a hot swap controller manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Linear Technology (Analog Devices)  
- **Part Number:** LT1640LIS8#TRPBF  
- **Package:** SOIC-8  
- **Operating Voltage Range:** 2.5V to 16.5V  
- **Maximum Supply Voltage:** 18V (absolute max)  
- **Current Limit Adjustment:** Adjustable via external sense resistor  
- **Fault Protection:** Overcurrent, undervoltage, and overvoltage  
- **Operating Temperature Range:** -40°C to +85°C  
- **Gate Drive Output:** Controls external N-channel MOSFET  

### **Descriptions:**  
The LT1640LIS8#TRPBF is a high-voltage hot swap controller designed to safely insert and remove boards from live backplanes. It provides inrush current control, fault protection, and power management for systems with supply voltages up to 16.5V.  

### **Features:**  
- **Hot Swap Functionality:** Allows safe board insertion/removal  
- **Adjustable Current Limit:** Uses an external sense resistor  
- **Undervoltage Lockout (UVLO):** Ensures proper operation voltage  
- **Overvoltage Protection (OVP):** Protects against excessive input voltage  
- **Fault Timer:** Prevents prolonged current limit conditions  
- **Power Good Output:** Indicates valid supply voltage  
- **Low Quiescent Current:** Efficient power management
