Description and Introduction

Latchable Positive High-Voltage Power-Limiting Hot Swap Controller 10-VSSOP -40 to 85 The TPS2490DGSG4 is a hot swap controller manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 9V to 80V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-VSSOP (DGS)  
- **Adjustable Current Limit:** Yes  
- **Fault Protection:** Overcurrent, Overtemperature, Undervoltage Lockout (UVLO)  
- **Gate Drive Voltage:** 10V (typical)  
- **Quiescent Current:** 1.5mA (typical)  

### **Descriptions:**
The TPS2490DGSG4 is a high-voltage hot swap controller designed to safely manage inrush current and provide robust protection for power systems. It allows boards to be inserted or removed from live backplanes without causing disruptions.  

### **Features:**
- **Wide Input Voltage Range (9V to 80V)** – Suitable for high-voltage applications.  
- **Adjustable Current Limit** – Allows precise control of inrush current.  
- **Fast Response to Faults** – Protects against short circuits and overloads.  
- **Programmable Fault Timer** – Prevents nuisance tripping.  
- **Undervoltage Lockout (UVLO)** – Ensures proper operation under low-voltage conditions.  
- **Thermal Shutdown** – Protects against overheating.  
- **Small 10-Pin VSSOP Package** – Saves board space.  

This device is commonly used in telecom, industrial, and server applications requiring hot swap functionality.
