Description and Introduction

0.7A, 2.7-5.5V Single Hi-Side MOSFET, Fault Report, Act-High Enable The TPS2051AD is a power distribution switch manufactured by Texas Instruments (TI) or Burr-Brown (BB). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Current:** 0.5A (continuous)  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **On-Resistance (RDS(ON)):** 95mΩ (typical) at 5V  
- **Quiescent Current:** 1µA (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **Overcurrent Protection Threshold:** Adjustable (default: ~1A)  
- **Fault Blanking Time:** 10ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**
The TPS2051AD is a single-channel power distribution switch designed for applications requiring controlled power management. It features integrated overcurrent protection and thermal shutdown to safeguard downstream circuits. The device is optimized for low-voltage systems and provides a controlled rise time to minimize inrush current.

### **Features:**
- **Adjustable Current Limit:** Allows customization for different load requirements.  
- **Fast Overcurrent Response:** Shuts off within microseconds in case of a fault.  
- **Thermal Shutdown Protection:** Prevents damage due to excessive heat.  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Controlled Turn-On:** Reduces inrush current during startup.  
- **Reverse Current Blocking:** Protects against backflow when disabled.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  

This information is based solely on the manufacturer's datasheet for the TPS2051AD.
