Description and Introduction

0.7A, 2.7 to 5.5V Dual (2 In/2 Out) High-Side MOSFET Switch IC, Fault Report, 1 Act-High, 1 Act-Low The TPS2081D is a power distribution switch manufactured by Texas Instruments (TI). Below 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)):** 80mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-8  

### **Descriptions:**  
The TPS2081D is a single-channel power-distribution switch designed for applications requiring precise current limiting, such as USB ports and other hot-swap systems. It integrates a low-resistance N-channel MOSFET and control circuitry to provide reliable power management.  

### **Features:**  
- **Adjustable Current Limit:** Protects against overcurrent conditions.  
- **Fast Overcurrent Response:** Shuts off quickly in fault conditions.  
- **Thermal Shutdown:** Prevents damage due to excessive heat.  
- **Controlled Slew Rate:** Reduces inrush current during turn-on.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Reverse Current Blocking:** Prevents backflow when disabled.  

This device is commonly used in USB hubs, portable devices, and other power distribution systems.
