 The INA226 is a current shunt and power monitor with an I²C or SMBUS-compatible interface. It monitors both a shunt voltage drop and bus supply voltage. Programmable calibration values, conversion times, and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts. The INA226 is a current shunt and power monitor with an I²C or SMBUS-compatible interface.
