Description and Introduction

Single Channel, Current-Limited USB Power Distribution Switch 5-SOT-23 -40 to 85 The TPS2051CDBVR 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:** 0.5A (typical)  
- **On-Resistance (RDS(ON)):** 95mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOT-23-5 (DBV)  
- **Fault Protection:** Overcurrent, thermal shutdown  
- **Enable Pin Logic:** Active-high  

### **Descriptions:**
The TPS2051CDBVR is a single-channel power-distribution switch designed for applications requiring precise current limiting, such as USB ports or other power-constrained systems. It integrates a low on-resistance N-channel MOSFET and offers protection features like thermal shutdown and overcurrent protection.

### **Features:**
- **Adjustable Current Limit:** Ensures safe operation under fault conditions.  
- **Fast Overcurrent Response:** Protects downstream circuitry.  
- **Low Standby Current:** Reduces power consumption when disabled.  
- **Controlled Slew Rate:** Minimizes inrush current during turn-on.  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs.  

This information is based solely on TI's datasheet for the TPS2051CDBVR.
