1 Abstract

The usage of Brushless-DC (BLDC) motors is becoming more commonplace in the automotive and industrial markets. Although more challenging to spin, Texas Instruments' BLDC motor drivers make spinning BLDC motors as simple as possible by reducing design complexity while improving system efficiency. TI offers a diverse portfolio of BLDC motor drivers that support various architectures, integration, and control methods to best suit a wide range of applications. The portfolio is grouped into driver, control, and safety families that each include key technologies. These technologies enable developers to design smaller and more efficient systems, decrease design complexity, and meet functional safety standards and certifications.
