INA226 is a shunt/power monitor with I²C or SMBUS compatible interface. The device monitors the shunt voltage drop and bus supply voltage. The programmable calibration value, conversion time and averaging function are combined with the internal multiplier to realize the direct reading of the current value (in amperes) and power value (in watts). The INA226 can sense current in the common-mode bus voltage range from OV to 36V, regardless of the power supply voltage.
