Description
The INA226 is a current
shunt and power monitor with an I2C™- or SMBUS-compatible interface. Thedevice
monitors both a shunt voltage drop and bussupply voltage. Programmable
calibration value,conversion times, and averaging, combined with aninternal
multiplier, enable direct readouts of current inamperes 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 330μA of supply current. The device is specified over the operating
temperature range between –40°C and125°C and features up to 16 programmable
addresses on the I2C-compatible interface
