  • DRV10970: Question about sensorless BLDC

    Resolved
    Part Number: DRV10970 Other Parts Discussed in Thread: MCF8329A , MCF8315C Tool/software: Hi, I have a question about sensorless BLDC. In addition to BEMF, it seems that magnetic linkage can also be used to estimate the rotor position, and do we have products…

  • RE: DRV10970: Question about the BLDC

    Resolved
    Hi Venkatadri, Thank you for your reply. Not refer to analog HALL sensor. It is a solution without sensor, just like the BEMF method to know the position of rotor. Have you ever heard it before? I give more detailed description in the new thread. You can give…

    Hi dear Venkatadri Thanks for your suggestions. As you guided, problem was about error in Hall placement and CMTMOD mismatch Best Regards Emre Kamışçı

  • DRV10970: Request to check earthquake damage in Taiwan

    Part Number: DRV10970 Hi, Our customer is using DRV10970PWPR parts, and the assembly location for this product is Taiwan. Could you check if this is affected? Best regards,

  • RE: DRV10970: Variation of output by direction

    Hi Higa-San, This shows motor phases and sensors are aligned in this combination. Can you also check changing FR value and if the motor works properly with this winding connection? Thanks and Best Regards, Venkatadri S

  • DRV10970: DRV10970: I try PWM control, but it doesn't work.

    TI Thinks Resolved
    Part Number: DRV10970 The hardware design was carried out as follows, and I am trying to control the motor speed by applying PWM to the DRV10970 IC, but the control is not working well. When PWM is applied, the motor responds slightly but does not…

  • RE: DRV10970: Absolute Maximum Ratingsfor PWM Pin

    Hi Andre Burkard, Problem 1: I guess, that I can apply up a 3.3V signal to the PWM pin, even if VINT is down, is this correct? Yes, PWM pin wakes up device. VINT rises when PWM is applied to wake the device from sleep mode. Problem 2: The power supply…

  • DRV10970: DRV10970

    Part Number: DRV10970 Hello When we look at the TIDUBH6 file, it seems that 3 single-output hall sensors are used. However, 6 signals, positive and negative, are input to the driver IC. What is the reason of this? How is it? TRANSLATE with x Engl…

  • RE: DRV10970: I try PWM control, but it doesn't work.

    Should be okay to have PWM pin pulled to GND on the PCB.
