Description and Introduction

0.345A, 2.7-5.5V Dual (1In/2Out) Hi-Side MOSFET, Fault Report, Act-Low Enable The TPS2046A is a power distribution switch manufactured by Texas Instruments (TI). Here 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)):** 95mΩ (typical) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Fault Current Limit:** 1.1A (typical)  
- **Reverse Current Blocking:** Yes  
- **Thermal Shutdown Protection:** Yes  
- **Undervoltage Lockout (UVLO):** Yes  
- **Package Options:** SOIC-8, MSOP-8  

### **Description:**  
The TPS2046A is a single-channel power-distribution switch designed for applications requiring precision current limiting, such as USB ports and other hot-swapable systems. It provides protection against overcurrent and thermal overload conditions.  

### **Features:**  
- **Adjustable Current Limit:** Ensures controlled power delivery.  
- **Fast Overcurrent Response:** Shuts off within microseconds.  
- **Low Standby Current:** Reduces power consumption when disabled.  
- **Built-in Soft-Start:** Minimizes inrush current.  
- **Reverse Input-Output Voltage Protection:** Prevents damage from reverse voltage conditions.  
- **ESD Protection:** Up to 2kV (HBM).  

This information is sourced from the official TI datasheet for the TPS2046A.
