UG952 (v1.1) January 30, 2013
Feature Descriptions
The AC701 board core and auxiliary voltages are listed in Table 1-25.
Monitoring Voltage and Current
Voltage and current monitoring and voltage control are available for the TI controlled
power rails through the Texas Instruments Fusion Digital Power Designer graphical user
interface (GUI). The two onboard TI UCD90120A power controllers (U8 at PMBus address
101 and U9 at address 102) are wired to the same PMBus. The PMBus connector, J2, is
provided for use with the TI USB Interface Adapter PMBus pod (TI part number EVM
USB-TO-GPIO) and associated TI Fusion Digital Power Designer GUI. This is the simplest
and most convenient way to monitor the voltage and current values for the power rail
listed in
Table 1-32 and Table 1-33.
In each of these the two tables (one per controller), the Power Good (PG) On Threshold is
the set-point at or above which the particular rail is deemed good. The PG Off Threshold is
the set-point at or below which the particular rail is no longer deemed good. The controller
