Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
A0 5 Digital input Address select. Connect to GND, V+, or leave floating.
A1 10 Digital input Address select. Connect to GND, V+, or leave floating.
ALERT/THERM2 7 Digital output Interrupt or SMBus alert output. Can be configured as a second THERM output.
Open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V.
D– 3 Analog input Negative connection to remote temperature sensor
D+ 2 Analog input Positive connection to remote temperature sensor
GND 6 Ground Supply ground connection
SCL 9 Digital input Serial clock line for SMBus.
Input; requires a pullup resistor to a voltage between 1.7 V and 3.6 V if driven by an open-drain output.
SDA 8 Bidirectional digital input-output Serial data line for SMBus. Open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V.
THERM 4 Digital output Thermal shutdown or fan-control pin.
Open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V.
V+ 1 Power supply Positive supply voltage, 1.7 V to 3.6 V
