Description

1

Positive Supply, 3 V to 3.6 V.

2

D1+

Positive Connection to the First Remote (Remote 1) Temperature Sensor.

3

D1−

Negative Connection to the First Remote (Remote 1) Temperature Sensor.

4

THERM

Open-Drain Output. This pin can be used to turn a fan on/off or throttle a CPU clock in the event of an

overtemperature condition. Requires pull-up resistor.

5

GND

Supply Ground Connection.

6

D2−

Negative Connection to the Second Remote (Remote 2) Temperature Sensor.

7

D2+

Positive Connection to the Second Remote (Remote 2) Temperature Sensor.

8

ALERT

/THERM2

Open-Drain Logic Output. This pin is used as interrupt or SMBus alert. May also be configured as a second

THERM output. Requires pull-up resistor.

9

SDATA

Logic Input/Output, SMBus Serial Data. Open-drain output. Requires pull-up resistor.

10

SCLK

Logic Input, SMBus Serial Clock. Requires pull-up resistor.
