8-bit I2C-bus and SMBus low power I/O port with interrupt and reset

5.2 Pin description

[1]

HVQFN16 package die supply ground is connected to both the VSS pin and the exposed center pad. The

VSS pin must be connected to supply ground for proper device operation. For enhanced thermal, electrical,

and board-level performance, the exposed pad needs to be soldered to the board using a corresponding

thermal pad on the board, and for proper heat conduction through the board thermal vias need to be

incorporated in the printed-circuit board in the thermal pad region.
