Diode_2 - Input
(CPU2 THERMDC)
Function
This is the negative input (current sink) from the CPU2 thermal
diode. Connected to THERMDC pin of Pentium processor or the
emitter of a diode connected MMBT3904 NPN transistor. Serves as
the negative input into the A/D for thermal diode voltage
measurements. A 100 pF capacitor is optional and can be
connected between REMOTE2 and REMOTE2+.
This is a positive connection to the CPU2 thermal diode. Serves as
the positive input into the A/D for thermal diode voltage
measurements. It also serves as a current source output that
forward biases the thermal diode. Connected to THERMDA pin of
Pentium processor or the base of a diode connected MMBT3904
NPN transistor. A 100 pF capacitor is optional and can be
connected between REMOTE2 and REMOTE2+.
Analog Input for +12V Rail 1 monitoring, for CPU1 voltage regulator.
External attenuation resistors required such that 12V is attenuated
to 0.927V.
Analog Input for +12V Rail 2 monitoring, for CPU2 voltage regulator.
External attenuation resistors required such that 12V is attenuated
to 0.927V.
Analog Input for +12V Rail 3, for Memory/3GIO slots. External
attenuation resistors required such that 12V is attenuated to 0.927V.
