Description and Introduction

0.345A, 2.7-5.5V Single Hi-Side MOSFET, Fault Report, Act-Low Enable The TPS2045DR is a power distribution switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Current:** 500mA (per channel)  
- **Number of Channels:** 4  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **On-Resistance (RDS(ON)):** 95mΩ (typical at 5V)  
- **Current Limit:** Adjustable (default 500mA)  
- **Fault Protection:** Overcurrent, thermal shutdown  
- **Package:** SOIC-16 (DR)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TPS2045DR is a quad-channel power-distribution switch designed for applications requiring multiple power rails. It provides controlled power switching with built-in protection features, including overcurrent and thermal shutdown.  

### **Features:**  
- **Adjustable Current Limit:** Default 500mA per channel  
- **Low Standby Current:** 1µA (typical)  
- **Fast Overcurrent Response:** <1µs  
- **Reverse Current Blocking:** Prevents backflow  
- **Thermal Shutdown Protection:** Prevents damage from overheating  
- **Controlled Slew Rate:** Reduces inrush current  

This device is commonly used in USB hubs, hot-swap applications, and power management systems.
