Ground input

There is an internal electrical connection between the exposed

thermal pad and VSS pin of the device. The exposed thermal pad

Exposed

must be connected to the same potential as the Vss pin on the

Thermal

Pad

–

printed circuit board. Do not use the thermal pad as the primary

PAD

ground input for the device. VSS pin must be connected to ground

at all times.
