The INA700 devices are digital power monitors specifically designed for current sensing applications. The INA700 devices report current, bus voltage, die temperature, power, energy and charge accumulation. The INA700 device at I2C address 0x44 measures power on the VR_INT_5V0 voltage rail and the device at I2C address 0x45 measures power on the VR_VCCINT_0V85 voltage rail. More information about the power system can be found in Monitoring Voltage and Current. More information about the INA700 devices and how to interact with them can be found at the TI website.
