Part Number: DRV10866 Hello,
We have a customer who is looking for the mechanical footprint data for this device. There is no mechanical data on the datasheet, and on the Find Packages page for the SON devices, all that appears is an image of the device…

My customer is using DRV10866. He has a problem. DRV10866 stops to drive motor suddenly. Please see the following picture. (Vcc = 5V) After stoping driving, DRV10866 can drive normally…
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…
The datasheet says that the speed can be controlled by VCC and PWM input. So when should I use VCC and when to use PWM? Besides, do they have the same resolution? The datasheet only says: "The PWM input signal resolution is less than 1%"

I have a question about DRV10866 FG signal start point Q1:Where does FG signal start from ? Please show the start point at this picture. The following picture is start up waveform. I think red line on the…
Hi Shimizu-san,
You are right, FG signal seems to align V phase after re synchronization of motor
I did some bench test and validated it. So whenever speed of motor is greater than 18 Hz, DRV10866 will jump open loop and FG will be synchronized to V …

Could you tell me how to enter standby mode DRV10866?
Is it that Input PWM is low? If this is correct, How long should the input signal be made Low?
Thanks
Shimizu

My customer is using DRV10866
Could you let me know the method of BEMF detection, please?
-> Compare voltage of COM pin and shut-off phase pin(W or U or V)?
