  • DRV8307: Motor not starting up at -15C

    Part Number: DRV8307 Tool/software: I have a design that functions well at temperatures -10C or higher. However, I have test that consistently fails on multiple samples at -15C. The motor simply does not start up, and the motor driver faults out. I can…

  • DRV8307: Controller IC was blown when the brake signal was set

    Part Number: DRV8307 Tool/software: Hi, I have a board using the DRV8307 and the application requires running the motor to 6000rpm. One of the motors we tried was a 57BL521 rated at 24VDC6000rpm, it was custom made for us from this company https://www…

  • DRV8307: DRV8307

    Part Number: DRV8307 Hi, I've designed a BLDC motor driver board with DRV8307. MOSFETs are FDS6670 and the motor is MAXON EC45 30 watt with hall sensor and encoder. I attached only hall sensors to the motor driver, not the encoder to anywhere. Arduino…

  • DRV8307: DRV8307

    Part Number: DRV8307 Other Parts Discussed in Thread: MCT8316Z , DRV10970 Hi, A dual output hall sensor is used in section 8.1.1 of the DRV8307 datasheet. I searched, but I could not find a double output (negative and positive) product in the market. Can…

  • DRV8307: How to increase motor torque with DRV8307？

    TI Thinks Resolved
    Part Number: DRV8307 I am using the DRV8307 to drive a BLDC (brushless DC) motor with 3 Hall sensors distributed at 120 degrees. The motor provides high torque at high speeds, but the torque is significantly reduced at low speeds. How can I increase the…

    Hi Annie, Do you still require further assistance on this? Please help mark the thread as resolved if there are no further questions. Thanks. Best Regards, Andrew

  • RE: DRV8307: jitter issue

    What I need is a mechanism to stop the motor without reporting an error when this happens, that is, when the Hall sensor signal is abnormal, the three-phase output is not commutated. As shown below: (0,1,2 represent three-phase output, 4,5,6 represent Hall…
