Description and Introduction

0.7A, 2.7-5.5V Triple (2In/3Out) Hi-Side MOSFET, Fault Report, Act-Low Enable The TPS2043A is a power distribution switch manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 0.5A per channel (3 channels)  
- **On-Resistance (RDS(ON)):** 80mΩ (typical) at 5V  
- **Overcurrent Threshold:** Adjustable (default 0.5A)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SOIC-16, TSSOP-16  

### **Descriptions:**  
The TPS2043A is a triple-channel power-distribution switch designed for applications requiring multiple power rails. It provides controlled power switching with built-in current limiting and thermal protection. Each channel operates independently, allowing selective power management.  

### **Features:**  
- **Triple-Channel Power Switch:** Three independently controlled 0.5A switches.  
- **Adjustable Current Limit:** Default 0.5A per channel with external resistor option.  
- **Fast Overcurrent Response:** Shuts off within microseconds during a fault.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Low Standby Current:** Typically 1µA when disabled.  
- **Reverse Current Blocking:** Prevents backflow when disabled.  
- **Controlled Rise Time:** Reduces inrush current during turn-on.  

This information is strictly factual from the TI datasheet for the TPS2043A.
