3 Description
The INA230 is a current-shunt and power monitor
with an I2C interface that features 16 programmable
addresses. The INA230 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 INA230 senses current on buses that vary from
0V to 36V, with the device powered from a single
2.7V to 5.5V supply, drawing 330μA (typical) of supply
current. The INA230 is specified over the operating
temperature range of –40°C to +125°C.
