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. Programmable calibration value, conversion times, and averaging combined with an internal multiplier enable direct readouts of current in amperes and power in watts.
●The INA231 senses current on buses 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.
