Notes on PCB design

We recommend to observe the following layout rules to avoid application problems with

ground and anomalous recirculation current.

The by-pass capacitors for the power and logic supply must be kept as near as possible to

the IC.

It's important to separate on the PCB board the logic and power grounds and the internal

charge pump circuit ground avoiding that ground traces of the logic signals cross the ground

traces of the power signals.

Because the IC uses the board as a heat sink, the dissipating copper area must be sized in
