Design Support


PCB design of motor drive systems is not trivial and requires special considerations and techniques to achieve the best performance. Power efficiency, high-speed switching frequency, low-noise jitter, and compact board design are few primary factors that designers must consider when laying out a motor drive system. Texas Instruments' DRV devices are ideal for such type of systems because they are highly integrated and well-equipped with protection circuitry. The goal of this application report is to highlight the primary factors of a motor drive layout when using a DRV device and provide a best practice guideline for a high performance solution that reduces thermal stress, optimizes efficiency, and minimizes noise in a motor drive application.
