Application information
A typical application using L6226Q is shown in
application are shown in

as short as possible in the layout. To increase noise immunity, unused logic pins are best
connected to 5 V (high logic level) or GND (low logic level) (see pin description). It is
recommended to keep power ground and Signal Ground separated on PCB.
