Open-drain; requires a pullup resistor to a voltage between 1.7V and 3.6V.

2

SCL

Digital I

 Serial clock line for SMBus.
Input; requires a pullup resistor to a voltage between 1.7V and 3.6V if driven by an open-drain output.

3

A1

Digital I

 Address select. Connect to GND, V+, or leave floating.

4

 V+

P

 Positive supply voltage, 1.7V to 3.6V.

5

D+

Analog I

 Positive connection to remote temperature sensor.

6

 D–

Analog I

 Negative connection to remote temperature sensor.

7

 THERM

Digital O

 Thermal shutdown or fan-control pin.
Open-drain; requires a pullup resistor to a voltage between 1.7V and 3.6V.

8

A0

Digital I

 Address select. Connect to GND, V+, or leave floating.

9

GND

G

 Supply ground connection.

10

 ALERT/ THERM2 Digital O Interrupt or SMBus alert output. Can be configured as a second THERM output.
Open-drain; requires a pullup resistor to a voltage between 1.7V and 3.6V.
