### **Descriptions:**  
The INA139QPWRQ1 is a precision current shunt monitor designed for high-side current sensing in automotive and industrial applications. It provides a fixed gain of 50 V/V, converting a small differential voltage across a shunt resistor into a ground-referenced output voltage.  

### **Features:**  
- **Wide Input Common-Mode Range:** 2.7V to 26V  
- **Low Quiescent Current:** 60 µA (typical)  
- **Fixed Gain:** 50 V/V  
- **High Bandwidth:** 500 kHz  
- **AEC-Q100 Qualified for Automotive Applications**  
- **Low Offset Voltage:** ±150 µV (maximum)  
- **Small TSSOP-8 Package**  
- **Overvoltage Protection (up to 30V)**  

This device is suitable for battery monitoring, motor control, and power management in harsh environments.
