D– A3 Analog input Negative connection to remote temperature sensors. Common for 8 remote channels.
GND A4 Ground Supply ground connection
SCL D4 Digital input Serial clock line for I2C- or SMBus compatible two-wire interface.
Requires a pullup resistor to a voltage between 1.7 V and 3.6 V (not necessarily V+) if driven by an open-drain output.
SDA C4 Bidirectional digital input/output Serial data line for I2C or SMBus compatible two-wire interface. Open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+.
THERM B3 Digital output Thermal shutdown or fan-control pin.
Active low; open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+. If this pin is not used it may be left open or grounded.
THERM2 C3 Digital output Second THERM output.
Active low; open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+. If this pin is not used it may be left open or grounded.
V+ D3 Power supply Positive supply voltage, 1.7 V to 3.6 V; requires 0.1-µF bypass capacitor to ground.
