Application note
EVAL6227QR demonstration board using a dual full-bridge L6227Q
for motor control applications
Introduction
This application note describes the demonstration board of the DMOS dual full-bridge
L6227Q designed for motor control applications. The board implements a typical application
that can be used as a reference design to drive two-phase bipolar stepper motors with
currents up to 1A DC, multiple DC motors and a wide range of inductive loads.
Thanks to the small footprint of the L6227Q (QFN 5 x 5 mm, 32-lead) the PCB is very
compact (27 x 32 mm).
