Description and Introduction

ExpressCard Single Power Interface Switch 20-QFN The TPS2231RGPTG4 is a power distribution switch manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Part Number:** TPS2231RGPTG4  
- **Package:** QFN (RGP)  
- **Number of Pins:** 20  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 1.5A (typical)  
- **On-Resistance (RDS(ON)):** 70mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Switching Type:** Load Switch  
- **Fault Protection:** Overcurrent, Thermal Shutdown  

### **Descriptions:**  
The TPS2231RGPTG4 is a single-channel, low-RDS(ON) power-distribution switch designed for applications requiring precise power management. It integrates a MOSFET switch with protection features to safeguard against overcurrent and overheating conditions.  

### **Features:**  
- **Adjustable Current Limit:** Allows customization for different load conditions.  
- **Fast Turn-On/Turn-Off:** Ensures quick response in power switching applications.  
- **Low Quiescent Current:** Optimized for battery-powered systems.  
- **Reverse Current Blocking:** Prevents backflow when the switch is off.  
- **Thermal Shutdown Protection:** Automatically disables the switch in case of excessive temperature.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
