Starterware/DRV8301: DRV8301 for driving a single Phase BLDC

Part Number: DRV8301
Other Parts Discussed in Thread: DRV8801, DRV8871, DRV8701

Tool/software: Starterware

Hello,

has anyone used the DRV8301 to drive a single phase brushless Motor?

We have the DRV8301-69-Kit and need to drive a single Phase BLDC Motor,

so I was looking into the possibility of Spinning it with the DRV8301-69-Kit.

Any comments, ideas, etc... ?

Greetings,

John

    Hi John,

    The DRV8301 is capable of driving a single phase brushless motor. While not having used the DRV8301 to drive the motor, we have created a reference design using the DRV8801, a brushed motor driver.

    Please see the link www.ti.com/.../TIDA-00875 as an example.

    Two half bridges are required to drive the motor, plus a hall sensor to commutate.

    Hi Duncan,

    Thanks for your response and suggestion. We found this reference design of yours and have ordered the boards to follow up on it. Since we already have the DRV8301-69-Kit board, it is also very tempting to use this board with modified software. I have combed the forums without success and as I take it from your answer, TI has not used the DRV8301 for a single Phase application. Any plans in that direction or have you heard of anyone else achieving similiar?

    Regards,
    John

    Hi John,

    I am not aware of a design or plans using the DRV8301 for a single phase application. We highlighted the brushed motor device to show it can be used for brushless applications also.

    As mentioned, there is nothing to prevent it from working. Most designs used a brushed motor predriver for higher currents (like the DRV8701) or a brushed motor driver with integrated FETs (like the DRV8801 or DRV8871) because of the cost of the unused circuitry.
