Application note

EVAL6230QR demonstration board

Introduction

This application note describes the demonstration board of the DMOS driver for the three-

phase brushless DC motor driver L6230Q. The board implements a typical application

which can be used as a reference design to drive three-phase brushless DC motors with

currents up to 1 A DC.

Thanks to the small footprint of the L6230Q (QFN 5x5 mm) the PCB is very compact (32x31

mm).
