The INA226 is a current shunt and power monitor with an I2C- or SMBUS-compatible interface. Thedevice monitors both a shunt voltage drop and bussupply voltage. Programmable calibration value, conversion times, and averaging, combined with aninternal multiplier, enable direct readouts of current inamperes and power in watts. ^^ High-Side or Low-Side Sensing ^^ Senses Bus Voltages From 0 V to 36 V ^^ The INA226 senses current on common-mode bus voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device operates from a single 2.7 -V to 5.5 -V supply, drawing a typical of 330A of supply current.
The device is specified over the operating temperature range between 40C and125C and features up to 16 programmable addresses on the I2C-compatible interface ^^
