Description and Introduction

Current-Limited, Power-Distribution Switches with Output Discharge resistor 8-MSOP-PowerPAD -40 to 85 The TPS2066DGNR-1 is a power distribution switch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 1A (typical)  
- **On-Resistance (RDS(ON)):** 80mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin MSOP (DGNR)  
- **Fault Protection:** Overcurrent, thermal shutdown, reverse current blocking  
- **Enable Control:** Active-high logic  

### **Descriptions:**
The TPS2066DGNR-1 is a single-channel power-distribution switch designed for applications requiring precise current limiting and protection. It integrates a low RDS(ON) MOSFET with control circuitry to provide efficient power management.  

### **Features:**
- **Adjustable Current Limit:** Protects downstream components from overcurrent conditions.  
- **Fast Overcurrent Response:** Shuts off within microseconds to prevent damage.  
- **Thermal Shutdown:** Prevents overheating by disabling the switch if temperatures exceed safe limits.  
- **Reverse Current Blocking:** Prevents backflow when the output voltage is higher than the input.  
- **Low Standby Current:** Consumes minimal power when disabled.  
- **Small Footprint:** Suitable for space-constrained applications.  

This device is commonly used in USB ports, portable electronics, and other power distribution systems requiring protection and control.  

(Note: Always refer to the official TI datasheet for the latest and most accurate details.)

Application Scenarios & Design Considerations

Current-Limited, Power-Distribution Switches with Output Discharge resistor 8-MSOP-PowerPAD -40 to 85

Alternative Part Number

  • MIC2026-1YM --: Dual-channel high-side power switch with current limiting, functionally similar to the TPS2066 dual switch and available in an SOIC package.
  • AP2311S-3.3 --: Single/dual high-side load switch with current limit and enable control, suitable as a functional replacement in power distribution designs.
  • FPF2006 --: IntelliMAX current-limited load switch offering comparable overcurrent protection and enable functionality for USB/power-rail applications.
