### **Descriptions:**  
The INA219AIDR is a high-side current shunt and power monitor with an I²C interface. It measures voltage, current, and power by sensing a small voltage drop across a shunt resistor.  

### **Features:**  
- Measures Bus Voltage, Current, and Power  
- High-Side or Low-Side Sensing  
- Programmable Calibration Value  
- Alert Function for Overcurrent Detection  
- Low Power Consumption (Typ. 350 µA)  
- Compatible with 3.3V and 5V Microcontrollers  

This device is commonly used in battery monitoring, power management, and industrial applications.
