Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the  
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect  
device reliability.  
NOTE: This device is ESD sensitive. Use standard ESD precautions when handling.

TACH2  
GND  
DRIVE1 Pin Drives Fan 1. Open−drain output. Requires a pullup resistor.  
Fan 1 Fan Speed Measurement Input. Connects to the fan’s TACH output to measure the fan speed.  
DRIVE2 Pin Drives Fan 2. Open−drain output. Requires a pullup resistor.  
Fan 2 Fan Speed Measurement Input. Connects to the fan’s TACH output to measure the fan speed.  
Ground for Analog and Digital Circuitry.  
VCC  
Power. Can be powered by 3.3 V standby power if monitoring in low power states is required.  
THERM  
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/REF  
FAN_FAULT: Open−Drain Output. Asserted low when one or both fans stall. Requires a pullup  
resistor to V . REF: Analog Input Reference for the THERM Input.

LOCATION  
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).

ALERT  
SDA  
Open−Drain Output. SMBusALERT pin. Alerts the system in the case of out−of−limit events, such as  
over temperature. Can be configured as sticky SMBus mode or comparator mode.  
Serial Bus Bidirectional Data. Connects to the SMBus master’s data line. Requires pullup resistor if  
not provided elsewhere in the system.  
SCL  
Serial SMBus Clock Input. Connects to the SMBus master’s clock line. Requires pullup resistor if not  
already provided in the system.
