Description and Introduction

Adjustable, Active High, Constant-Current, Current-Limited Power-Distribution Switch 6-WSON -40 to 85 The TPS2551DRVR is a power-distribution switch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Continuous Current Limit:** 0.5A (adjustable)  
- **On-Resistance (RDS(ON)):** 70mΩ (typical)  
- **Quiescent Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-pin SOT-23 (DRV)  

### **Descriptions:**  
The TPS2551DRVR is a precision-adjustable current-limited power-distribution switch designed for applications requiring controlled power management. It provides overcurrent protection, thermal shutdown, and reverse-current blocking.  

### **Features:**  
- **Adjustable Current Limit:** Set via an external resistor (50mA to 500mA range).  
- **Fast Overcurrent Response:** Shuts off in <2µs during a short circuit.  
- **Reverse Current Blocking:** Prevents backflow when disabled.  
- **Thermal Shutdown Protection:** Automatically disables output if overheating occurs.  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Controlled Turn-On:** Reduces inrush current.  

This information is sourced from TI's official datasheet for the TPS2551DRVR.
