Description and Introduction

0.345A, 2.7-5.5V Dual (1In/2Out) Hi-Side MOSFET, Fault Report, Act-Low Enable The TPS2046D is a power distribution switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 0.5A (typical)  
- **On-Resistance (RDS(ON)):** 95mΩ (typical) at 5V  
- **Overcurrent Protection:** Fixed current limiting  
- **Thermal Shutdown Protection:** Yes  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The TPS2046D is a single-channel power-distribution switch designed for applications requiring precision current limiting, such as USB ports and other hot-swap systems. It integrates a low on-resistance N-channel MOSFET and provides protection against overcurrent and thermal overload.  

### **Features:**  
- Adjustable current limit (fixed for TPS2046D)  
- Fast overcurrent response (µs range)  
- Reverse current blocking  
- Controlled rise time to reduce inrush current  
- Under-voltage lockout (UVLO) protection  
- ESD protection  

For detailed datasheet information, refer to the official TI documentation.
