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).
