Description and Introduction

2.7-5.5V Dual In/Single Out MOSFET, 0.5A Main/0.1A Aux Input, Act-High Enable, Industrial Temp. The TPS2105D is a power-distribution switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 500mA (typical)  
- **Low On-Resistance (RDS(ON)):** 80mΩ (typical) at 5V  
- **Fast Turn-On Time:** 20µs (typical)  
- **Undervoltage Lockout (UVLO):** Ensures proper operation when input voltage is too low  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions and Features:**  
- **Power-Distribution Switch:** Designed for applications requiring controlled power switching.  
- **Current Limiting:** Protects the circuit from excessive current draw.  
- **Reverse Current Blocking:** Prevents backflow when the output voltage is higher than the input.  
- **Low Quiescent Current:** Helps conserve power in battery-operated devices.  
- **Enable Pin (EN):** Allows external control of the switch.  
- **Applications:** USB power management, portable devices, and hot-swap power supplies.  

This device is optimized for power management in space-constrained and battery-powered systems.
