Description and Introduction

Adjustable, Active High, Constant-Current, Current-Limited Power-Distribution Switch 6-SOT-23 -40 to 85 The TPS2551DBVT is a power-distribution switch manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Continuous Current Limit:** Adjustable (default 0.5A to 1.5A)  
- **On-Resistance (RDS(ON)):** 80mΩ (typical)  
- **Quiescent Current:** 35µA (typical)  
- **Shutdown Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6 (DBV)  

### **Descriptions:**  
- The TPS2551DBVT is a precision adjustable current-limited power-distribution switch.  
- It provides protection for systems against overcurrent and short-circuit conditions.  
- Features reverse current blocking when disabled.  

### **Features:**  
- **Adjustable Current Limit:** Set via an external resistor.  
- **Fast Overcurrent Response:** <5µs response time.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Controlled Rise Time:** Reduces inrush current.  
- **Reverse Current Blocking:** Prevents backflow when disabled.  
- **Low Standby Current:** Enhances power efficiency.  

This device is commonly used in USB ports, portable devices, and other power management applications.
