2 D+ Positive Connection to Remote Temperature Sensor.
3 D– Negative Connection to Remote Temperature Sensor.
THERM THERM is an open-drain output that can be used to turn a fan on/off or throttle a CPU clock in the event of
4
an overtemperature condition. Requires pull-up to V
5 GND Supply Ground Connection.
ALERT
6 Open-Drain Logic Output Used as Interrupt or SMBus Alert.
7 SDATA Logic Input/Output, SMBus Serial Data. Open-drain output. Requires pull-up resistor.
8 SCLK Logic Input, SMBus Serial Clock. Requires pull-up resistor.
