Description

An interface that is I2C? or SMBUS compliant, the INA226AIDGSR is a current shunt and power monitor. Shunt voltage drop and bus supply voltage are both monitored by the gadget. Direct readouts of current in amps and power in watts are possible thanks to programmable calibration value, conversion timings, and averaging, as well as an internal multiplier.

Independent of the supply voltage, the INA226AIDGSR measures current on common-mode bus voltages that range from 0 V to 36 V. With a single supply voltage ranging from 2.7 to 5.5 volts, the device may run while using a typical supply current of 330 μA. A maximum of 16 programmable addresses are available on the I2C-compatible interface, and the device is specified to operate between -40°C and 125°C.
