Description
+3V VDD power. It is also a voltage monitor
channel. This pin has internal divider resistors
to scale down the input voltage for analog
voltage measurement.
Bypass with the parallel combination of 10μF
(electrolytic or tantalum) and 0.1μF (ceramic)
bypass capacitors.
This pin is power for W83795G. It is also a
voltage monitor channel. This pin has internal
divider resistors to scale down the input
voltage for analog voltage measurement.
Bypass with the parallel combination of 10μF
(electrolytic or tantalum) and 0.1μF (ceramic)
bypass capacitors.
VBAT supplies power for CASEOPEN.
Besides, it is also a voltage monitor channel for
+3V on-board battery. This pin has internal
divider resistors to scale down the input
voltage for analog voltage measurement.
CASEOPEN detection. An active low input
from an external device when chassis is
Intruded. This signal will be latched even the
chassis is closed.
Intel® CPU Vtt power.
It is also a voltage monitor channel.
Detect range is 0~2.048V
Intel® CPU PECI interface. (default)
AMD® CPU SB-TSI interface.
AMD® CPU SB-TSI interface
CPU THERMTRIP# signal. (default)
When CPU assert THERMTRIP# signal,
W83795G will latch this event.
System reset input. (default)
When this pin is asserted to low, Watch-dog
timer will be reset.
Fan tachometer input
This is a bi-directional pin.
As an input signal, when it is pull-ed to low, the
