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 pullup 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 pullup resistor to V
DD
.
7
SDATA
Logic Input/Output, SMBus Serial Data. Open-drain Output. Requires pullup resistor.
8
SCLK
Logic Input, SMBus Serial Clock. Requires pullup resistor.
NOTE: The ground slug on 3? package can be left unconnected.
