Application note

EVAL6229QR demonstration board using the L6229Q DMOS

driver for a three-phase BLDC motor control application

Introduction

This application note describes the EVAL6229QR demonstration board for the L6229Q

DMOS fully integrated three-phase brushless DC motor driver. The board implements a

typical application that can be used as a demonstration platform for driving three-phase

brushless DC motors with currents up to 1 A DC.

Thanks to the small footprint of the L6229Q (QFN 5x5 mm), the board is a very compact

30x32 mm.
