Description and Introduction

Single Current Limited Power Distribution Switch The TPS2061DGNR is a power distribution switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current:** 1A  
- **On-Resistance (RDS(ON)):** 70mΩ (typical)  
- **Overcurrent Protection:** Adjustable (1.5A typical)  
- **Thermal Shutdown:** Yes  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin MSOP (DGNR)  

### **Descriptions:**  
- The TPS2061DGNR is a single-channel power-distribution switch with integrated current-limiting and thermal protection.  
- It is designed for applications requiring controlled power switching, such as USB ports, hot-swap circuits, and power management in portable devices.  

### **Features:**  
- **Adjustable Current Limit:** Protects against short circuits and excessive loads.  
- **Fast Overcurrent Response:** Minimizes voltage droop during fault conditions.  
- **Low Standby Current:** Reduces power consumption when disabled.  
- **Reverse Current Blocking:** Prevents backflow when the switch is off.  
- **Controlled Rise Time:** Reduces inrush current during turn-on.  
- **Enable Pin (Active High):** Allows for external control of the switch.

Application Scenarios & Design Considerations

Single Current Limited Power Distribution Switch

Alternative Part Number

  • MIC2026-1YM --: Dual-channel high-side power switch with current limiting, functionally similar to the TPS2061 and available in an SOIC package.
  • AP2553W6-7 --: Single-channel adjustable current-limited power switch with enable, a common drop-in style alternative for USB power distribution.
  • LM3526MX-L --: Dual-port USB power switch with overcurrent protection from the same vendor, suitable when a different package and pinout are acceptable.
