- **Current Limit:** Adjustable  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The TPS2044BDRG4 is a quad-channel power-distribution switch designed for applications requiring multiple power switches with controlled turn-on and fault protection. It is commonly used in USB hubs, hot-plug power supplies, and other power management systems.  

### **Features:**  
- **Controlled Turn-On:** Minimizes inrush current during startup.  
- **Overcurrent Protection:** Limits output current to safe levels.  
- **Thermal Shutdown:** Prevents damage due to excessive heat.  
- **Low Standby Current:** Reduces power consumption when inactive.  
- **Fast Overcurrent Response:** Quickly shuts off during faults.  
- **Wide Operating Voltage:** Supports 2.7V to 5.5V applications.  

This device is suitable for applications requiring reliable power switching and protection.
