  • DRV8849: Generation of Sinusoidal wave at the output of DRV8849 Driver.

    TI Thinks Resolved
    Part Number: DRV8849 Tool/software: Hi , We tested the waveform at a lower Vref value i.e. of 50 (0.65V) , and we observed that it is still not purely sinusoidal. Interestingly, a pure sine wave is observed only at a Vref value of 0. Kindly review and…

  • DRV8849: Driving a motor using DRV8849 with microstepping of 1/128.

    TI Thinks Resolved
    Part Number: DRV8849 Tool/software: Hi, i am using the stm32 controller to generate PWM pulse for rotating the motor with 0.9 degree per step with microstepping of 1/128. i am checking the pulse frequency as per calculation as 102400 Hz to rotate the…

  • DRV8849: Charge Pumping Troubleshooting

    Part Number: DRV8849 Other Parts Discussed in Thread: DRV8834 , DRV8845 , Hello, I recently got back my PCB from JLCPCB, which uses two DRV8849 drivers to control four bipolar stepper motors. I previously worked with the TI DRV8834, which had internal…

  • DRV8849: Driving a motor using a DRV8849.

    Part Number: DRV8849 Tool/software: Our application uses the DRV8849 driver to control motor rotation. However, we're encountering a motor noise issue during operation with a load of 0.4 Nm. Could you please suggest optimal driver settings to reduce the…

  • DRV8849: Noise Issue in Driver with Decay mode.

    Part Number: DRV8849 Hello, We are experiencing significant motor audible noise when DECAY = GND (0E) , but the motor operates quietly when DECAY is left open (Hi-Z) . According to the datasheet, ripple-control mode (DECAY = GND) should reduce noise…

  • DRV8849: nSleep and Enable timing limitation during start-up

    Part Number: DRV8849 Hello Expert, Is there any limitation between nSleep pin and Enable pin control during start-up? My understanding this there isn't limitaion due to Enable pin is ignored as long as nSleep is low or nSleep is high with elappsing…

  • DRV8849: Braking of the stepper motor using DRV8849.

    Part Number: DRV8849 Tool/software: Hi all, We are using DRV8849 in our design and would like to achieve braking functionality when the stepper motor connected at the output is not rotating. Please suggest how we can achieve the same. Regards…
