Name and Function/Connection
Positive input (current source) from the first remote thermal diode.
Serves as the positive input into the A/D. Connected to
THERMDA pin of Pentium processor or the base of a diode
connected MMBT3904 NPN transistor.
Negative input (current sink) from the first remote thermal diode.
Serves as the negative input into the A/D. Connected to
THERMDC pin of Pentium processor or the emmiter of a diode
connected MMBT3904 NPN transistor.
Positive input (current source) from the first remote thermal diode.
Serves as the positive input into the A/D. Connected to
THERMDA pin of Pentium processor or the base of a diode
connected MMBT3904 NPN transistor.
Negative input (current sink) from the first remote thermal diode.
Serves as the negative input into the A/D. Connected to
THERMDC pin of Pentium processor or the emmiter of a diode
connected MMBT3904 NPN transistor.
Input for monitoring tachometer output of fan 1.
Input for monitoring tachometer output of fan 2.
Input for monitoring tachometer output of fan 3.
Input for monitoring tachometer output of fan 4. If in Address
Select Mode, determines the SMBus address of the LM96000.
Fan speed control 1. When in XOR tree test mode, functions as
XOR Tree output.
Fan speed control 2.
Fan speed control 3. Pull to ground at power on to enable
Address Select Mode (Address Select pin controls SMBus
address of the device).
