Description and Introduction

Dual 1A Current-Limited, Power-Distribution Switches 8-MSOP-PowerPAD -40 to 85 The TPS2066DGNRG4 is a power distribution switch manufactured by Texas Instruments (TI). Below are its key 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)  
- **Number of Channels:** 1  
- **Fault Protection:** Overcurrent, thermal shutdown, reverse current blocking  
- **Enable Logic:** Active-high enable pin  

### **Descriptions:**
- The TPS2066DGNRG4 is a single-channel power-distribution switch designed for applications requiring precise current limiting and protection.  
- It integrates a low RDS(ON) N-channel MOSFET for efficient power switching.  
- Suitable for USB ports, hot-swap applications, and power management in portable devices.  

### **Features:**
- **Adjustable Current Limit:** Protects downstream circuits from overcurrent conditions.  
- **Fast Overcurrent Response:** Reacts quickly to short-circuit events.  
- **Thermal Shutdown:** Prevents damage due to excessive heat.  
- **Reverse Current Blocking:** Prevents reverse current flow when disabled.  
- **Low Quiescent Current:** Minimizes power consumption in standby mode.  
- **Small Footprint:** 8-pin MSOP package for space-constrained designs.

Application Scenarios & Design Considerations

Dual 1A Current-Limited, Power-Distribution Switches 8-MSOP-PowerPAD -40 to 85

Alternative Part Number

  • MIC2026-1YM --: Dual-channel high-side power switch with similar current rating and enable control, functionally equivalent to the TPS2066 dual switch.
  • AP2151SG-13 --: Single-channel current-limited high-side switch; use two devices or select the dual variant for equivalent load-switching behavior.
  • LM3526MX-L --: Dual high-side power switch from a different TI family with comparable voltage and current specifications, offering an in-family alternative.
