BLDC/PMSM Motor Driver Overcomes Design and Microcontroller Supply Issues

Current semiconductor supply chain shortages can be a challenge for motor driver and controller designers. Employing a fully integrated solution allows the designer to obtain a high performance microcontroller coupled with gate drivers, DC/DC switchers, LDO regulators, differential amplifiers, single ended amplifiers, etc.

Semiconductor shortages in the supply chain can disrupt the plans of the best motor driver and controller designers. It becomes even more challenging when their designs use many discrete components, such as those required to drive tri-phase BLDC and PMSM motors. Failing to procure a single one of these components renders the entire solution non-manufacturable.

There is a better and easier alternative. Designers have the option to employ a highly integrated system-on-chip product which packages all of the electronic blocks required to drive and control typical tri-phase BLDC motors. By packaging the microcontroller along with the different power and analog blocks, designers save both on cost as well as space, while delivering high performance solutions despite a semiconductor shortage.

Key Takeaways

  • Successfully navigate through semiconductor shortages by using a highly integrated motor driver SOC.
  • Discover how to drive high performance, tri-Phase BLDC/PMSM motors while achieving the utmost efficiency.
  • Understand how integration helps high-power battery-based applications and delivers on performance at reduced cost.
  • Learn all of the blocks required to drive triphase BLDC/PMSM motors through sensor or sensor-less, six-step trapezoidal or field-oriented control algorithms.
