    Design INA226
    SBOS547A – JUNE 2011 – REVISED AUGUST 2015 INA226 High-Side or Low-Side Measurement,
    Bi-Directional Current and Power Monitor with I2C Compatible Interface
    1 Features 3 Description The INA226 is a current shunt and power monitor
    with an I2C™-or SMBUS-compatible interface. The
    device monitors both a shunt voltage drop and bus
    supply voltage. Programmable calibration value,
    conversion times, and averaging, combined with an
    internal multiplier, enable direct readouts of current in
    amperes and power in watts. 1 Senses Bus Voltages From 0 V to 36 V
    High-Side or Low-Side Sensing
    Reports Current, Voltage, and Power
    High Accuracy:
    – 0.1% Gain Error (Max)
    – 10 μV Offset (Max)
    Configurable Averaging Options
    16 Programmable Addresses ...
