Application information

A typical application using L6226 is shown in Figure 14. Typical component values for the

application are shown in Figure 8. A high quality ceramic capacitor in the range of 100 to

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

Bridge B respectively when an over current is detected (see overcurrent protection). The two

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.
