The INA226-Q1 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.
The INA226-Q1 senses current on common-mode bus voltages that can vary from
0 V to 36 V, independent of the supply voltage. The device operates from a
single 2.7-V to 5.5-V supply, drawing a typical of 330 μA of supply current.
The device is specified over the operating temperature range between –40°C and
125°C and features up to 16 programmable addresses on the
