4 Conclusion

As using BLDC motors is becoming more common in applications today, understanding the architecture options and key considerations when choosing a specific BLDC motor driver is important to get the most out of a design, whether that be for size optimization, increasing thermal efficiency, lessening commutation complexity, or lowering total BOM cost. As discussed in this document, TI’s BLDC motor driver portfolio supports various architectures and use cases to enable designers of all applications to get the most out of their BLDC systems.
