Description and Introduction

3.3V LDO + Dual Switch For USB, DSP, And Portable Applications, Active-Low Enables The TPS2147IDGQ is a power-distribution switch manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Output Current:** 1.5A  
- **On-Resistance (RDS(ON)):** 80mΩ (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin MSOP (DGN)  

### **Descriptions:**  
- The TPS2147IDGQ is a single-channel, current-limited power-distribution switch designed for USB and other hot-swap applications.  
- It integrates a low-resistance N-channel MOSFET for efficient power management.  
- Features include overcurrent protection, thermal shutdown, and controlled rise time to minimize inrush current.  

### **Features:**  
- **Current Limiting:** Protects against short circuits and excessive loads.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **Fast Overcurrent Response:** Reacts quickly to fault conditions.  
- **Controlled Rise Time:** Reduces inrush current during startup.  
- **Low Standby Current:** Enhances power efficiency.  
- **Reverse Current Blocking:** Prevents backflow when disabled.  

This device is commonly used in USB ports, portable electronics, and power management systems.

- **Shutdown Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Pin MSOP (DGQ)  

### **Descriptions:**  
- The TPS2147IDGQ is a single-channel, current-limited power-distribution switch.  
- It provides protection against overcurrent and thermal shutdown.  
- Features an enable (EN) pin for power management control.  

### **Features:**  
- **Current Limiting:** Protects the input supply from excessive loads.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **Fast Short-Circuit Response:** Limits fault current quickly.  
- **Controlled Slew Rate:** Reduces inrush current during turn-on.  
- **Reverse Current Blocking:** Prevents current flow from output to input when disabled.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.  

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