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.
The INA226 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\xC2°C and features up to 16 programmable addresses on
the I2C-compatible interface.
