DESCRIPTION

SDA

Digital I/O

Serial data line for SMBus.

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

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

Digital I

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

V+

Positive supply voltage, 1.7V to 3.6V

D+

Analog I

Positive connection to the remote temperature sensor

D–

Analog I

Negative connection to the remote temperature sensor

THERM

Digital O

Thermal shutdown or fan-control pin.

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

Digital I

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

GND

Supply ground connection

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
