4.5.3.3 Power Monitoring
INA226 power monitor devices are used to monitor current and voltage of various power rails of J721E
processor. The device reports current, voltage and power to J721E processor through I2C interface. Four
Terminal High Precision shunt resistors are provided, and the values are calculated based on load current.
