Three phase motor drive: Cross for AA585B

Other Parts Discussed in Thread: DRV8323R, MSP430FR2355

MD team,

I stumbled across this Jotrin AA585B part for a bone drill, and wondered if you have any knowledge of it?

I assume it's a three phase motor drive but can't access a datasheet of it, does TI have anything that could compete?

Thank you,

Drake

    Hi Drake,

    Nick & Ranita gave me a heads-up about this last night. After quite a bit of scouring the internet, I also cannot find any mention of this part, what it does, or how it works.

    If you can figure out the supply voltage we may be able to give a recommendation. Off the top of my head is DRV8323R which can be implemented in a system like this design.

    Thanks,

    Matt

    Matt,

    Thank you for the quick response and looking into this so thoroughly. I too cannot find any information on this device.

    The DRV8323R is the perfect fit for this application, however when I shared this TI Reference Design with our field team that works in this space, they shared that the design is becoming outdated as we have a newer hall effect sensor and MSP430 to offer.

    Are there plans to update this TI Design?

    Best,

    Drake

    Hi Drake,

    No we do not intend to update this design.

    The Hall Sensors are not on the design (they get embedded in the motor).

    The MCU is general purpose; it is intended to show how the system works. You can always point to a newer and better MSP430 like the MSP430FR2355. The solution from a motor drive perspective is the same either way.

    Thanks,

    Matt
