Part Number: DRV10866 Other Parts Discussed in Thread: , DRV10987 , DRV10983 , DRV10964 Hi,
I am trying to use this device for a small brushless motor (Faulhaber 0308...B series). When unloaded, the device works great (much better than other third party…
Part Number: DRV10866 Hello E2E, When circuit architected at fig.4(from datasheet) that which the direction of rotation of the motor CW or CCW? Is the standard input PWM frequency to the DRV10866 25-kHz? Best regards, ACGUY
Part Number: DRV10866 Other Parts Discussed in Thread: DRV10974 Dear TI Team
I am looking for a suitable motor driver to drive the following gimbal motors.

For example, I think DRV10866 is good. If…
Part Number: DRV10866 Hi Team,
My customer has the DRV10866 running in an early prototype but they are finding that they need to reduce the jitter.
While currently spinning at 1800 RPM (30Hz) and the once around jitter is about 18us peak-to-peak based…
Rolf,
Without known exact operation condition, I can only guestimate, I would expect less than 3% speed variation with exact same motor under same load condition and temperature across many DRV10866.
Theoretically, you can estimate the speed but…
Part Number: DRV10866 Hi, team,
My customer checks the lock protection. He get the attached wave form while motor is locked. Current is following for about 3-A and FG output ON and OFF irregularly during locking. Could you please give me advice why…
Part Number: DRV10866 Hello E2E,
I have a question in regards to using the FG pin on the DRV10866.
Is the FG signal derived directly from BEMF detection (some analog comparator output) or is it gets synced to an internal clock?
The reason for…
3) You can use either edge as this device measures the true bemf zero crossing.
4) The FG is generated at every bemf zero crossing. The FG should be closely 50% duty cycle, unless speed changes very rapidly.
Part Number: DRV10866 Hi,
I'd like to know the FG output and Lock detection feature of DRV10866. 1. Depend on customer application and environments, the DRV10866 cannot detect the point BEMF cross zero due to noise. In this case, how will FG output…
Part Number: DRV10866 Other Parts Discussed in Thread: DRV10963 , Can you please explain the ramifications of choosing a value of resistor in the resistor net that simulates a common lead for a 3-wire BLDC as explained in section 8.1 of the datasheet…
