Description and Introduction

0.345A, 2.7-5.5V Single Hi-Side MOSFET, Fault Report, Act-Low Enable 8-SOIC 0 to 85 The TPS2045ADG4 is a power distribution switch manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **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:** SOIC-8  
- **Fault Protection:** Overcurrent, Thermal Shutdown  
- **Enable Input:** Active-high logic control  

### **Descriptions:**  
The TPS2045ADG4 is a single-channel power-distribution switch designed for applications requiring precision current limiting, such as USB ports and other hot-swap systems. It provides controlled power switching with protection features to prevent damage from overcurrent or excessive temperatures.  

### **Features:**  
- **Adjustable Current Limit:** Protects downstream circuits from overcurrent conditions.  
- **Fast Overcurrent Response:** Limits fault current quickly to prevent damage.  
- **Thermal Shutdown:** Disables output if temperature exceeds safe limits.  
- **Low Standby Current:** Minimizes power consumption when disabled.  
- **Reverse Current Blocking:** Prevents current flow from output to input when disabled.  
- **Controlled Rise Time:** Reduces inrush current during turn-on.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
