BLDC / EC Motor Driver

ADI Trinamic’s integrated 3-phase driver ICs for brushless DC (BLDC) motors and PMSM allow you to design highly efficient drives. The drivers allow for control for sine-commutation of 3-phase motors using 6-line control or SPI from the CPU. Power MOSFETs, a charge-pump, and current feedback options are all packed on the 3-phase driver for BLDC and PMSM motors, making it a highly efficient solution for powerful drives.

Real-Time Feedback and Control
Under common conditions, the position of a stepper motor is deterministic and predictable, but what about when the motor does not behave as expected? Many devices demand real-world, real-time feedback from the motor for added safety and monitoring purposes. Closed-loop operation of motors can furthermore increase the efficiency and overall performance of your application, for example by reducing the current when the motor is on standby and increasing the current under load conditions. As such, closed-loop control increases the system’s control reliability and flexibility.

FOC Servo Out of the Box
Field oriented control (FOC) is the most efficient way to drive motors. It transforms actual phase currents from stator-fixed to field-synchronous coordinate systems by using two mathematical transformations. The resulting coordinate system has only two dimensions (magnetic flux and torque), which are orthogonal components and can be visualized as a vector; hence FOC may sometimes be called vector control. FOC was originally developed for high end applications and has traditionally been difficult to implement. ADI Trinamic™ technology offers FOC as an easy-to-use hardware building block.

We Transform Digital Information into Physical Motion
Transforming digital information into physical motion is not as simple as just translating data into movement. Motion control technology must be flexible to support evolving device capabilities, efficient to satisfy space constraints of shrinking footprints, and of course, easy to implement, whether it’s driving advanced robotics and automation, battery-powered medical devices, IoT, or any other application. ADI Trinamic™ motion control technology elevates essential motor characteristics into competitive advantages by transforming digital information into perfect physical motion.
