Description and Introduction

Dual In/Single Out Autoswitching Power MUX, Manual/Auto Sw, Adj. Cur Limit, Adj. Vol Threshold The TPS2111PW is a power multiplexer manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS2111PW  
- **Type:** Power Multiplexer  
- **Package:** TSSOP-8  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Current:** Up to 500mA

- **Switching Control:** Automatic or Manual (via control pin)  
- **Features:** Low quiescent current, seamless switching between power sources  

### **Descriptions:**  
The TPS2111PW is a power multiplexer designed to switch between two power supplies (such as a battery and an adapter) with minimal voltage drop. It ensures uninterrupted power delivery by automatically selecting the higher voltage source or allowing manual control.  

### **Features:**  
- **Automatic or Manual Power Source Selection**  
- **Low On-Resistance (0.6Ω typical)**  
- **Wide Input Voltage Range (2.7V to 5.5V)**  
- **Low Quiescent Current (10µA typical)**  
- **Overvoltage Protection (OVP)**  
- **Seamless Transition Between Power Sources**  
- **Thermal Shutdown Protection**  
- **Available in TSSOP-8 Package**  

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

Application Scenarios & Design Considerations

Dual In/Single Out Autoswitching Power MUX, Manual/Auto Sw, Adj. Cur Limit, Adj. Vol Threshold

Alternative Part Number

  • TPS2113APW --: Same TPS211x family power mux in the same TSSOP package with similar pinout and current rating, offering a close functional drop-in with slightly different feature set.
  • TPS2115APW --: Related TI power multiplexer in the same package and pin-compatible family, suitable when adjustable current limit and auto-switch behavior are needed.
  • MAX4995AAUT+T --: Alternative current-limit/power-switch IC from a different vendor series that can serve similar power-path switching roles, though pinout and package differ so layout changes are required.
