Description and Introduction

0.345A, 2.7-5.5V Single Hi-Side MOSFET, Fault Report, Act-High Enable The TPS2055AD 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)  
- **Quiescent Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-8  

### **Description:**
The TPS2055AD 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 applications.

### **Features:**
- **Adjustable Current Limit:** Protects downstream circuits from overcurrent conditions.  
- **Thermal Shutdown:** Prevents damage due to excessive heat.  
- **Fast Overcurrent Response:** Quickly disconnects power in fault conditions.  
- **Low Standby Current:** Minimizes power consumption when disabled.  
- **Reverse Current Blocking:** Prevents backflow when the switch is off.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  

This information is based solely on the manufacturer's datasheet. For detailed application guidelines, refer to TI's official documentation.
