Description
DRIVE Pin Drives the Fan. Open-drain output. Requires a pull-up resistor.
Fan Speed Measurement Input. Connects to the fan’s TACH output to measure the fan speed.
Open-Drain Active Low Output. Asserts low whenever a measurement goes outside its programmed limits,
if not masked. Automatically goes high again when the measured parameter falls back within its limits.
No Connect.
Ground for Analog and Digital Circuitry.
Power. Can be powered by 3.3 V standby power, if monitoring in low power states is required.
Can be configured as an overtemperature interrupt output, or as an input to monitor PROCHOT output of
an INTEL CPU. A timer measures assertion times on the THERM pin (either input or output).
FAN_FAULT: Open-Drain Output. Asserts low whenever the fan stalls.
REF: Analog Input Reference for THERM input.
Cathode Connection for the Thermal Diode or Diode-Connected Transistor.
Anode Connection for the Thermal Diode or Diode-Connected Transistor.
No Connect.
No Connect.
8-Level Analog Input. Used to determine the correct SMBus version and the SMBus address (in fixed-and-
discoverable mode), and to set the LLL bits in the UDID (in ARP-capable mode).
Open-Drain Output. Alerts the system in the case of out-of-limit events such as overtemperature. Can be
reset only with software.
Serial Bus Bidirectional Data. Connects to the SMBus master’s data line. Requires a pull-up resistor, if one is
not provided elsewhere in the system.
Serial SMBus Clock Input. Connects to the SMBus master’s clock line. Requires a pull-up resistor, if one is
not provided elsewhere in the system.
