Description and Introduction

Autoswitching Power Mux The TPS2115APWR 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:** TPS2115APWR  
- **Type:** Power Multiplexer  
- **Package:** TSSOP-8  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Output Current:** 1.5A  
- **On-Resistance (RDS(ON)):** 70mΩ (typical)  
- **Switching Threshold:** Adjustable via external resistors  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:** Automatic and manual switchover, low quiescent current  

### **Descriptions:**  
The TPS2115APWR is a dual-input, single-output power multiplexer designed for power source selection in portable and battery-powered applications. It allows seamless switching between two power sources (such as a battery and an adapter) while preventing reverse current flow.  

### **Features:**  
- **Seamless Power Source Transition:** Automatically switches between two power inputs.  
- **Low On-Resistance:** Minimizes power loss (70mΩ typical).  
- **Adjustable Switching Threshold:** Allows customization of switchover voltage.  
- **Manual Control Option:** Supports manual override via an external signal.  
- **Reverse Current Blocking:** Prevents backflow from output to input.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  
- **Overvoltage Protection:** Safeguards against input overvoltage conditions.  

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

Application Scenarios & Design Considerations

Autoswitching Power Mux

Alternative Part Number

  • TPS2113APWR --: Same TPS211x family power mux with auto-switchover and very similar pinout and current rating, making it a close drop-in substitute with minor threshold differences.
  • TPS2114APWR --: Sister device in the same power-multiplexer family with comparable voltage range and current capability, differing mainly in switching threshold configuration.
  • LTC4412ES6 --: Alternative PowerPath controller from a different vendor that performs similar automatic supply switchover for dual-input power systems, though package and pinout differ.
  • TPS2115PWR --: Same TPS2115 family power mux in TSSOP package without the A variant; pin-compatible and functionally equivalent for most auto-switchover designs.
  • MAX40200AUK+T --: Ideal-diode power mux from a different vendor offering comparable automatic source switching; requires layout review but is a viable cross-vendor alternative.
