General 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.
