  • DRV10866EVM: Start-up sequence intermittent

    TI Thinks Resolved
    Part Number: DRV10866EVM Other Parts Discussed in Thread: DRV10866 Hi, I am using the DRV10866EVM as a debug setup for my motor control. I am having start-up issues with one of two motors. The first motor has a phase-phase resistance of about 6.3 ohms…

  • DRV10866EVM: Start-up sequence intermittent with high inertia

    Resolved
    Part Number: DRV10866EVM Other Parts Discussed in Thread: DRV10866 Hi, I am using the DRV10866 in a closed loop application. The current limit resistor is the default 3.8k. With a light inertia the motor starts up quickly and robustly. With a higher inertia…

  • RE: DRV10866: Usage for slow starting motors

    Hi Micheal, Thanks for the fast reply. The supply voltage is 3.7V and I kept all the default component values on the DRV10866EVM board, so the CS resistor is 3.8k setting a current limit of 820mA. The motor I'm using has a phase to phase resistance of…

  • DRV10964: When PWM pin held high, does driver operate motor?

    TI Thinks Resolved
    Part Number: DRV10964 Other Parts Discussed in Thread: DRV10866 , , TPS22860 , DRV10866EVM , , DRV10963 DRV10866 has this feature. It is not clear to me from reading the datasheet that the DRV10964 has this feature. IOW, does the PWM pin need to be pulsed…

  • DRV10866 About FG waveform

    Resolved
    Other Parts Discussed in Thread: DRV10866EVM , DRV10866 Hi My customer is using DRV10866EVM. He uses motor whose pole pairs is 4. He has a issue. When motor speed is high, FG waveform is missing teeth. I think it exceeds RPM spec on which DRV10866 can…

  • DRV10866: Fails to start motor sometimes, when pulsing motor

    Part Number: DRV10866 Other Parts Discussed in Thread: , DRV10963 Using the DRV10866EVM (evaluation module board with motor provided in the kit) and a EZ MSP430 Launchpad (the USB dongle with separable target board.) I jumpered Vcc, Gnd, and a motorEnable…

  • RE: DRV10866 with WYE wired BLDC

    Motor Phase to phase resistance 20Ohm VCC 5V - USB powered. Rcs? If you are talking about R6 in DRV10866EVM (which I use now) manual says 2.6KOhm Hoyoung
