The INA233 device is a current, voltage, and power monitor with an I2C-, SMBus-, and PMBus-compatible interface that is compliant with digital bus voltages from 1.8 V to 5.0 V. The device monitors and reports values for current, voltage, and power. The integrated power accumulator can be used for energy or average power calculations. Programmable calibration value, conversion times, and averaging when combined with an internal multiplier enable direct readouts of current in amperes and power in watts.
The INA233 senses current on common-mode bus voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device operates from a single 2.7-V to 5.5-V supply, drawing a typical supply current of 310 µA in normal operation. The device can be placed in a low-power standby mode where the typical operating current is only 2 µA. The device is specified over the operating temperature range between –40°C and +125°C and features up to 16 programmable addresses.
