Texas Instruments INA230 Bidirectional Current / Power Monitor
Texas Instruments INA230 Bidirectional Current Shunt/Power Monitor with I2C interface features 16 programmable addresses and can monitor 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. INA230 current/power monitor senses current on buses that vary from 0V to +28V with the device powered from a single +2.7V to +5.5V supply, drawing 330µA (typical) of supply current. INA230 is specified over the -40°C to +125°C operating temperature range. Texas Instruments INA230 is ideal for use in smartphones, tablets, servers, and more.
