The FMCP HSPC (J51 and J53) VADJ pins are wired to the programmable rail VADJ_FMC. The
VADJ_FMC rail is programmed to 1.50V by default. The VADJ_FMC rail also powers the

Monitoring Voltage and Current

Twenty rails have a TI INA226 PMBus power monitor circuit with connections to the rail series
current sense resistor. This arrangement permits the INA226 to report the sensed parameters
separately on the PMBus. The rails equipped with the INA226 power monitors are shown in the
power system table in
As described in PMC MIO[46:47] I2C0
controllers and the INA226 power monitors via the U33 TCA9548A bus switch. All PMBus
controlled Infineon regulators are tied to the PMBUS_SDA/SCL PMBus, while the INA226 power
monitors are split across PMBUS1_INA226_SDA/SCL and PMBUS2_INA226_SDA/SCL.
