Description and Introduction

CURRENT-LIMITED POWER-DISTRIBUTION SWITCHES The TPS2051ADRG4 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:** 0.5A (typical)  
- **On-Resistance (RDS(ON)):** 95mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 8-Pin SOIC (D)  

### **Descriptions:**
- The TPS2051ADRG4 is a single-channel power switch with integrated current-limiting protection.  
- It is designed for applications requiring controlled power distribution, such as USB ports, hot-swap circuits, and power management in portable devices.  
- The device features thermal shutdown and overcurrent protection to safeguard connected circuits.  

### **Features:**
- **Adjustable Current Limit:** Protects against excessive load currents.  
- **Fast Overcurrent Response:** Shuts off quickly in fault conditions.  
- **Low Standby Current:** Minimizes power consumption when disabled.  
- **Reverse Current Blocking:** Prevents backflow when the switch is off.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

CURRENT-LIMITED POWER-DISTRIBUTION SWITCHES

Alternative Part Number

  • MIC2026-1YM --: Dual-channel high-side power switch with current limiting, functionally similar to the TPS2051A single-channel switch; different series and manufacturer make it easy to distinguish.
  • AP2191SG-13 --: Single-channel current-limited high-side power switch in SO-8, comparable load-switch function and pin-compatible footprint for many TPS2051A applications.
  • LM3526MX-L --: TI current-limited high-side power switch with similar voltage and current ratings, offered as an alternative family to the TPS2051A while remaining from the same vendor.
