    IRMCK099 on a new design
    Hello All

    I am looking to use the IRMCK099 in a new design, but I have the following question:

    I assume that the IRMCK099 will run BLDC motors just as well as the PMSM's? I have found no documentation stating that the IRMCK099 is happy with BLDC however they do state that targets the drone market - which uses BLDC.

    The data sheet answers your question: IRMCK099 contains the flexible Tiny Motion Control Engine (TinyMCE) for sensorless control of permanent magnet motors (which is PMSM) over the full speed range. The drive signals for the PMSM and the BLDCM are different.
    The BLDC is driven trapezoidally, while the PMSM is driven sinusoidally. So, the answer is: no, you can't. You can visit the "Motor and Drives" page presenting different solutions for permanent magnet synchronous motor and brushless DC motor.
