Description and Introduction

High-Side Measurement Current-Shunt Monitor with Dual Comparators The INA206A is a high-side current shunt and power monitor manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 18V  
- **Common-Mode Voltage Range:** -16V to +80V  
- **Current Sense Amplifier Gain:** 20 V/V (fixed)  
- **Bandwidth:** 500 kHz  
- **Quiescent Current:** 900 µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** SOIC-8  

### **Descriptions:**  
The INA206A is designed for high-side current sensing in applications such as power management, battery monitoring, and motor control. It provides accurate voltage output proportional to the current flowing through an external shunt resistor.  

### **Features:**  
- Wide common-mode voltage range (-16V to +80V)  
- Fixed gain of 20 V/V  
- Low offset voltage (±250 µV max)  
- High bandwidth (500 kHz)  
- Low quiescent current (900 µA typical)  
- Rail-to-rail output swing  
- Enhanced PSRR (Power Supply Rejection Ratio)  

The device is suitable for industrial, automotive, and telecom applications requiring precise current monitoring.

Application Scenarios & Design Considerations

High-Side Measurement Current-Shunt Monitor with Dual Comparators

Alternative Part Number

  • INA219AIDR --: Same vendor current-shunt monitor family with similar I2C interface and high-side sensing, widely available and often used as a functional substitute.
  • INA226AIDGSR --: TI current/power monitor with comparable high-side sensing and I2C output; different series name and pinout, suitable when design can be adapted.
  • ACS712ELCTR-20A-T --: Hall-effect current sensor from a different manufacturer and series, offering galvanically isolated current measurement as an alternative approach.
