VSS 5 5 5 5 – Ground input

There is an internal electrical connection between the exposed

thermal pad and V

pin of the device. The exposed thermal pad

Exposed

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

Thermal Pad Pad Pad 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.
