Description and Introduction

Latchable Positive High-Voltage Power-Limiting Hot Swap Controller The TPS2490DGS is a hot-swap controller manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.9V to 18V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Pin VSSOP (DGS)  
- **Current Limit Range:** Adjustable via external resistor  
- **Fault Protection:** Overcurrent, undervoltage, and overtemperature  
- **Gate Drive Voltage:** Adjustable for external N-channel MOSFET  
- **Quiescent Current:** Typically 1.2mA  

### **Descriptions:**
The TPS2490DGS is designed for hot-swap applications, allowing safe insertion and removal of circuit boards from live systems. It provides inrush current control, fault protection, and adjustable current limiting to protect power supplies and loads.

### **Features:**
- **Adjustable Current Limit:** Set via an external sense resistor.  
- **Programmable Fault Timer:** Prevents nuisance tripping.  
- **Fast Response to Overcurrent:** Protects downstream circuits.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Overtemperature Protection:** Shuts down if excessive heat is detected.  
- **Controlled Turn-On:** Soft-start feature minimizes inrush current.  

For more details, refer to the official TI datasheet.
