### **Key Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current:** 1.5A  
- **Low On-Resistance:** 70mΩ (typical)  
- **Automatic Switchover:** Prioritizes between two power sources  
- **Manual Control Option:** Allows user selection via control pin  
- **Low Quiescent Current:** 1µA (typical) in standby mode  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin TSSOP (PW)  

### **Descriptions:**  
The TPS2115APWRG4 is designed to manage power sources in battery-powered and portable applications. It automatically selects between two power inputs based on priority or manual control, ensuring uninterrupted power delivery.  

### **Features:**  
- Seamless transition between power sources  
- Reverse current blocking  
- Overcurrent protection

Application Scenarios & Design Considerations

Autoswitching Power Mux 8-TSSOP -40 to 85

Alternative Part Number

  • TPS2115APWR --: Same TPS2115A power mux in TSSOP-8 package; the G4 suffix only denotes lead-free/RoHS green packaging, so this is functionally identical and the closest drop-in replacement.
  • TPS2113APWR --: Sister device in the TPS2113A family with the same pinout and package; offers similar auto-switching power mux behavior with slightly different current-limit threshold, suitable when exact limit is not critical.
  • MAX4995AAUT+T --: Alternative current-limit/power-switch IC from a different vendor and series, usable as a cross-vendor substitute for power-path switching applications where TI supply is unavailable.
  • TPS2114APWR --: Sister device in the TPS211xA family with similar auto-switching behavior and TSSOP-8 footprint; usable when slightly different switching thresholds are acceptable.
