Technical Data
6.5 Power Supply, Fan and Monitoring
Supply voltage
3.3V / 12V via PCIe card edge connector
Power consumption
A total power consumption of 25W must not be exceeded.
Maximum allowed power consumption also heavily depends
on adequate cooling/airflow.
Max. current on logic power rails:
I
max
I
max
(5V) = 5A
Max. current on auxiliary power rails:
I
max
(+12V) = 400mA
I
max
(-12V) = -150mA
Per default main power will be taken from PCIe card edge's
12V rail.
As an option 12V supply rail can be alternatively fed from an
external source through an auxiliary connector (see chapter
7.9). In this situation the 12V connection to the card edge has
to be disconnected by removing 0-Ohm resistors.
See block diagram for details on internal power supply rails
(Figure 1)
Over current protection
none, all supply rails are short circuit protected
Thermal protection
2x DS1631A under PMC/XMC site
The upper threshold is programmed to 60°C.
Fan placement
fan is placed below PMC/XMC site.
Fan type
Sunon, 40mm x 40mm x 6mm
(GM0504PEV1-8.GN)
Fan control
none, full speed
Fan monitoring
current sense
Protection circuit
PIM, PMC/XMC and PCIe/PCI bridge are turned off in case of
an over temperature condition. A power cycle of the carrier is
required to return to normal operation.
In case of a fan or temperature error the red LED is turn on.
