Description and Introduction

0.7A, 2.7-5.5V Quad (2 In/4 Out) Hi-Side MOSFET, Fault Report, Act-High Enable The TPS2054D 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 per Channel:** 500mA  
- **On-Resistance (RDS(ON)):** 95mΩ (typical) at 5V  
- **Number of Channels:** 4  
- **Overcurrent Protection:** Adjustable (internal 1.5A limit per channel)  
- **Thermal Shutdown Protection:** Yes  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The TPS2054D is a quad-channel power-distribution switch designed for applications requiring multiple power rails. It provides controlled power switching with protection features such as overcurrent and thermal shutdown. Each channel operates independently and is suitable for USB ports, hot-swap applications, and power sequencing.  

### **Features:**  
- **Independent Enable Control** for each channel  
- **Fast Overcurrent Response** (<1µs)  
- **Low Standby Current** (<1µA typical)  
- **Undervoltage Lockout (UVLO)**  
- **Reverse Current Blocking**  
- **ESD Protection** (up to 2kV HBM)  

This device is commonly used in USB hubs, portable devices, and industrial systems requiring reliable power management.
