Description and Introduction

Autoswitching Power Mux The TPS2111APWRG4 is a power multiplexer manufactured by Texas Instruments (TI)/Burr-Brown (BB).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Current:** Up to 1A  
- **Low On-Resistance (RDS(ON)):** 70mΩ (typical)  
- **Automatic or Manual Switchover Control**  
- **Low Quiescent Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin TSSOP (PW)  

### **Descriptions:**  
The TPS2111APWRG4 is a dual-input, single-output power multiplexer designed for seamless power source switching between two supplies. It is commonly used in battery-powered applications where automatic or manual power source selection is required.  

### **Features:**  
- **Seamless Transition:** Prevents voltage drops during switchover.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Reverse Current Blocking:** Prevents backflow between inputs.  
- **Fast Switching:** Minimizes disruption during power source changes.  
- **Overvoltage Protection:** Protects downstream circuitry.  

This device is suitable for applications such as portable electronics, USB power switching, and backup power systems.

Application Scenarios & Design Considerations

Autoswitching Power Mux

Alternative Part Number

  • TPS2111APW --: Same TPS2111A power mux in the same TSSOP-8 package without the G4 lead-free/RoHS suffix; functionally identical and widely available.
  • TPS2113APW --: Pin-compatible TPS211x family power mux with similar voltage/current ratings and adjustable current limit; a close functional substitute in the same package.
  • TPS2115APW --: Another member of the TPS211x power-mux family in the same TSSOP package, offering comparable automatic switchover behavior for power-path applications.
  • TPS2113APWR --: Pin-compatible power mux from the same TPS211x family with similar voltage/current ratings; check current-limit setting differences before use.
  • TPS2115APWR --: Another member of the TPS211x power-mux family in the same package, offering comparable automatic switchover behavior as a drop-in style alternative.
