Product Description

The INA231 is a current-shunt and power monitor with a 1.8-V compliant I2C interface that features 16 programmable addresses. The INA231 monitors both shunt voltage drops and bus supply voltage, providing increased protection by asserting the ALERT pin if the values are outside the programmed range. Programmable calibration value, conversion time, 

and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts, thus reducing host processing.

The INA231 senses current on bus voltages that vary from 0 V to 28 V, with the device powered from a single 2.7-V to 5.5-V supply, drawing 330 μA (typical) of supply current. The INA231 is specified over the operating temperature range of –40°C to +125°C.

The INA231 is available in two versions: the INA231A starts up performing continuous conversions of the shunt and bus voltage, whereas the INA231B starts up in low-current, power-down mode.
