36V, 16-bit, ultra-precise i2c & pmbus output current/voltage/power/energy monitor w/alert

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 1.8V to 5.0V. 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 0V to 36V, independent of the supply voltage. The device

operates from a single 2.7V to 5.5V supply, drawing a typical supply current of

310µA in normal operation. The device can be placed in a low-power standby mode

where the typical operating current is only 2µA. The device is specified over the

operating temperature range between –40°C and +125°C and features up to 16

programmable addresses.
