2.6 SMBus Interface (SMBus)
This interface allows a host computer to interact with an SMBus interface device such as a battery monitor
device through a 2-wire SMBus interface. Connect the data, clock, and a ground reference (VSS) to a
target device.
Pin Name Description
1.1 VSS Ground return/reference for SMBus interface.
1.2 SCL SMBus clock. Pulled up to 3.3 V with a 20-kΩ resistor. Uses bus acceleration in
positive direction to allow for a larger pullup resistor.
1.3 SDA SMBus data. Pulled up to 3.3 V with a 20-kΩ resistor. Uses bus acceleration in
positive direction to allow for a larger pullup resistor.
1.4 VOUT 1 Optional voltage output (future expansion)
