3 Texas Instruments' Brushless-DC Motor Drivers

TI’s Brushless DC Motor Driver portfolio supports various combinations of the architecture and use cases discussed above. The portfolio is divided into four groups: Gate Drivers (DRV8x and DRV3x family), Integrated MOSFET Drivers (DRV831x family), Integrated Control Drivers (MCx family), and Full Integration (MCx831x and DRV10x family). Each family supports industrial and automotive grade devices and comes in a variety of packages, variants, and integrations.

The following sections will provide details about the key technologies that each family supports. To learn more about the specific products in each family, visit ti.com/bldc.
