PRODUCTION DATA.
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. |
Thermal Pad(1) | -- | -- | The exposed thermal pad of the HKU package should be connected to a wide ground plane for effective thermal conduction. |
