Overview

The INA219EVM is a demonstration kit for the INA219 high-side current and power monitor, which utilizes an I2C interface. It provides an easy-to-use platform for evaluating the IC's ability to measure shunt voltage, current, and power over a common-mode range of 0V to 26V.

Why Choose This Part

The platform features a 12-bit ADC for high-resolution measurements and supports both I2C and SMBus communication protocols. It allows for high-side current sensing even at common-mode voltages significantly higher than the 3V to 5.5V supply voltage.

Applications

Battery Management Systems
Monitoring discharge rates and state-of-charge in portable electronics or battery-backed systems.
Power Distribution Units
Tracking real-time power consumption and voltage drops across different rails in a rack or enclosure.
Precision Power Profiling
Characterizing the current draw of low-power embedded devices across various sleep and wake cycles.
