Pin Number

Description

1

ADDR/THERM

Logic output pin that can be used to turn on/off a fan or throttle a CPU clock

in the event of an overtemperature condition. This is an open-drain output.

This pin is sampled following power-up and the value of the pull-up resistor

determines the SMBus slave address (see Table 1-1). Total capacitance on

this pin must not exceed 100 pF, and the pull-up resistor must be connected

2

GND

Ground pin

Supply Voltage pin, 3.0V to 3.6V

4

SMCLK

SMBus Clock Input pin

5ALERT/THERM2

Logic Output pin used as interrupt, SMBus alert or as a second THERM

output. This is an open-drain output.

6

SMDATA

SMBus Data Input/Output pin, open-drain output
