Product overview

Overview

INA219 is a digital current-shunt and power-monitor family that measures both shunt voltage and bus voltage and reports current, voltage, and calculated power over an I2C or SMBus-compatible interface. It is widely used in battery rails, power-distribution monitoring, and embedded telemetry designs where buyers need to protect software assumptions, package compatibility, and calibration behavior before approving substitutes or open-market supply paths.
