INA226 is a current shunt and power monitor with I2C or SMBUS compatible interface. The device simultaneously monitors the parallel voltage drop and the bus power supply voltage. The programmable calibration value, conversion time and average value are used in conjunction with the internal multiplier to directly read the current in amperes and the power in watts. The device has up to 16 programmable addresses on the I2C compatible interface.
