Description and Introduction

Dual Channel Precision Adjustable Current-Limited Power Switches 10-VSON -40 to 85 The TPS2561DRCT is a power-distribution switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 1.5A (typical)  
- **On-Resistance (RDS(ON)):** 70mΩ (typical at 5V)  
- **Quiescent Current:** 30µA (typical)  
- **Shutdown Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Pin VSON (DRC)  

### **Descriptions:**  
The TPS2561DRCT is a single-channel load switch designed for power distribution in portable and battery-powered applications. It provides controlled power switching with current limiting, thermal shutdown, and reverse current blocking.  

### **Features:**  
- **Adjustable Current Limit:** Configurable via an external resistor  
- **Fast Overcurrent Response:** Protects downstream circuits  
- **Reverse Current Blocking:** Prevents backflow when disabled  
- **Thermal Shutdown Protection:** Safeguards against overheating  
- **Controlled Turn-On:** Reduces inrush current  
- **Low Quiescent Current:** Optimized for battery-powered applications  

This device is commonly used in USB ports, power rails, and other applications requiring controlled power distribution.
