Description

1

Positive Supply, 3 V to 3.6 V.

2

D+

Positive Connection to Remote Temperature Sensor.

3

D−

Negative Connection to Remote Temperature Sensor.

4

THERM

Open-Drain Output. 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

ALERT/THERM2

Open-Drain Logic Output Used as Interrupt or SMBus ALERT. This can also be configured as a second

THERM output. Requires pull-up resistor.

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.
