Application information
A typical application using L6226 is shown in
application are shown in
200 nF should be placed between the power pins (VS
L6226 to improve the high frequency filtering on the power supply and reduce high
frequency transients generated by the switching. The capacitors connected from the

length 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.
