Table 5-1 Pin Functions
| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| ALERT/ THERM2 | 6 | Digital output | Interrupt or SMBus alert output. Can be configured as a second THERM output. Open-drain; requires pullup resistor to 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 | 5 | Ground | Supply ground connection. |
| SCL | 8 | Digital input | Serial clock line for SMBus. Input; requires pullup resistor to voltage between 1.7 V and 3.6 V if driven by open-drain output. |
| SDA | 7 | Bidirectional digital input-output | Serial data line for SMBus. Open-drain; requires pullup resistor to voltage between 1.7 V and 3.6 V. |
| THERM | 4 | Digital output | Thermal shutdown or fan-control pin. Open-drain; requires pullup resistor to voltage between 1.7 V and 3.6 V. |
| V+ | 1 | Power supply | Positive supply voltage, 1.7 V to 3.6 V. |
