Description and Introduction

Single-Channel Current-Limited Power Distribution Switch The TPS2041BDGNRG4 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 MSOP (DGN)  

### **Descriptions:**  
- The TPS2041BDGNRG4 is a single-channel, current-limited power-distribution switch designed for USB and other hot-plug applications.  
- It provides controlled power switching with built-in protection features.  
- The device includes thermal shutdown and overcurrent protection.  

### **Features:**  
- **Current Limiting:** Protects the input supply from excessive currents.  
- **Thermal Shutdown:** Prevents damage due to overheating.  
- **Fast Overcurrent Response:** Quickly shuts off during fault conditions.  
- **Low Standby Current:** Minimizes power consumption when disabled.  
- **Controlled Rise Time:** Reduces inrush current during turn-on.  
- **Reverse Current Blocking:** Prevents current flow from output to input when disabled.  

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