Flexible Portfolio of BLDC Motor Control Devices


Are you looking for a high-reliability, high-efficiency and high power-to-size ratio motor? The obvious solution is a Brushless DC (BLDC) motor. It shares many of the same torque and speed characteristics with the Brushed DC (BDC) motor but does not include the brushes. Technically, it is a Permanent Magnet Synchronous Motor (PMSM), but it's named Brushless DC as it operates from a DC power supply using an inverter with a simple commutation method and that there are no brushes involved. In some cases, the stator windings are constructed to match the non-sinusoidal commutation.

Brushless DC (BLDC) Motor Control

The BLDC motor’s simpler commutation method allows a wide range of our products to be used to control it, from 8-bit PIC® and AVR® microcontrollers (MCUs), to the MTD650x family of dedicated BLDC driver chips, to advanced dsPIC® Digital Signal Controllers (DSCs) and PIC32MK and SAM Arm® Cortex®-M0 based MCUs for sophisticated applications. Selecting the device that is best suited for your application depends on the performance, cost and efficiency you are trying to achieve in your design. Our comprehensive development ecosystem for BLDC motor control enables you to get started with your application quickly.

Typical Applications


  • Anti-lock braking systems
  • Disk drive servos
  • Throttle controls

  • Fuel pumps
  • Oil pumps

FPGAs for Multi-Axis Motor Control


Build safe and reliable multi-axis deterministic motor control on a single System-on-Chip (SoC) FPGA. FPGAs provide many advantages for motor control applications, including:

  • Compact solution to save board space and reduce product size
  • Motor speeds exceeding 100,000 RPM for sensorless Field-Oriented Control (FOC).
  • Low latency of 1 μs for FOC loop from ADC measurement to PWM generation allows switching frequencies up to 500 kHz
  • Design flexibility with modular IP suite
  • Advanced safety features such as rotor slip and overload detection and overcurrent protection
  • SoC integration of system functions reduces Total Cost of Ownership (TCO)
