INA230 is a 28-V, Bi-Directional, Zero-Drift, Low-/High-Side, I2C Out Current/Power Monitor with Alert

This post is sponsored by Texas Instruments.

The INA230 is a current-shunt and power monitor with an I2C interface that features 16 programmable addresses.

The device has high- or low-side sensing and 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 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. It is specified over the operating temperature range of –40°C to +125°C, and has high accuracy with 0.5% gain error (maximum) and 50-µV offset (maximum).

TI's INA230 is available in a 3-by-3-mm, 16-pin QFN package. It has many potential applications. Among these are smartphones, tablets, servers, computers, power management, battery chargers, power supplies, and test equipment.
