Description and Introduction

Dual In/Single Out Autoswitching Power MUX, Auto Sw, Adj. Cur Limit, Adj. Vol Threshold, Sw Status The TPS2113PWR is a power multiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range (VIN1, VIN2):** 2.7V to 5.5V  
- **Output Current:** Up to 1.5A continuous  
- **On-Resistance (RDS(ON)):** 85mΩ (typical)  
- **Switching Threshold:** Adjustable via external resistors  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin TSSOP (PWR)  

### **Descriptions:**  
The TPS2113PWR is an automatic power multiplexer that seamlessly switches between two power sources (VIN1 and VIN2) based on priority or voltage thresholds. It is designed to prevent reverse current flow and ensure uninterrupted power delivery.  

### **Features:**  
- **Automatic or Manual Switching:** Supports both priority-based and controlled switching.  
- **Low Power Consumption:** Quiescent current of 15µA (typical).  
- **Reverse Current Blocking:** Prevents backflow when one input is disconnected.  
- **Fast Switching:** Minimizes power interruption during transitions.  
- **Overvoltage Protection:** Tolerates input voltages up to 6V.  
- **Small Footprint:** Suitable for space-constrained applications.  

This device is commonly used in battery-powered systems, USB power switching, and redundant power supplies.

Application Scenarios & Design Considerations
