Description and Introduction

Single-Channel Current-Limited Power Distribution Switch The TPS2041B 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)  
- **Overcurrent Protection:** Fixed current limiting  
- **Thermal Shutdown Protection:** Yes  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Options:** SOT-23-5  

### **Descriptions:**  
The TPS2041B is a single-channel power-distribution switch designed for applications requiring precise current limiting and thermal protection. It is commonly used in USB ports, hot-swap circuits, and other power management systems.  

### **Features:**  
- **Adjustable Current Limit:** Fixed at 0.5A  
- **Fast Overcurrent Response:** Protects downstream circuits  
- **Low Standby Current:** Reduces power consumption  
- **Reverse Current Blocking:** Prevents backflow when disabled  
- **Controlled Rise Time:** Reduces inrush current  
- **ESD Protection:** Up to 2kV (HBM)  

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

Application Scenarios & Design Considerations

Single-Channel Current-Limited Power Distribution Switch

Alternative Part Number

  • MIC2026-1YM --: Dual-channel current-limiting power distribution switch with similar current-limit and enable functionality, commonly used as a TPS2041B substitute in USB power switching.
  • AP2552W6-7 --: Single-channel current-limited power switch with adjustable current limit and thermal shutdown, functionally comparable to the TPS2041B.
  • SY6280AAC --: Low-voltage current-limiting load switch with enable and fault flag, suitable as a cost-effective alternative for TPS2041B power distribution applications.
