UG887 (v1.2.1) March 11, 2014
Feature Descriptions
FMC_VADJ Voltage
The FMC VADJ rail is fixed at 1.8V (U63 V
OUT
B VCC1V8).
Monitoring Voltage and Current
6.
Voltage and current monitoring and control are available for selected power rails
through Texas Instruments' Fusion Digital Power graphical user interface. The three
onboard TI power controllers (U42 at address 52, U43 at address 53, and U64 at
address 54) are wired to the same PMBus. The PMBus connector, J5, is provided for use
with the TI USB Interface Adapter PMBus pod (TI part number EVM USB-TO-GPIO),
which can be ordered from the
website and the associated
TI Fusion Digital Power Designer GUI also downloadable from
. This is the simplest and most convenient way to monitor the voltage and current
values for the power rail listed in
.
In each of these the three 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 internally OR's these PG conditions together and drives an output PG pin high
only if all active rail PG states are “good”. The On and Off Delay and rise and fall times are
relative to when the board power on-off slide switch SW12 is turned on and off.
defines the voltage and current values for each power rail controlled by the
UCD9248 PMBus controller at address 52 (U42).
