Voltage and current monitoring and control for the Intersil power system is available through either the VCU128 system controller or the Intersil PowerNavigator software GUI. The VCU128 system controller is a simple and convenient way to monitor the voltage and current values for the power rails listed in the following table. The Intersil programmable power controllers listed in the table can also be accessed through the 2x3 male pin header J1. Using this connector requires the Intersil ZLUSBEVAL3Z USB to PMBus adapter. This adapter cable can be ordered from the Intersil website (see References). The associated Intersil PowerNavigator software GUI can be downloaded from the Intersil website. The Intersil programmable controller and INA226 power monitor I2C bus mapping is shown in the following table.
