Part Number: DRV10866 I've seen the pwm resolution discussed in three questions but nobody has asserted what the actual resolution is in bits. The data sheet says < 1%.
I need the actual # bits to compare with other devices and to compute the non…
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…
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? There…
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 the question…
Part Number: DRV10866 Hi
I'm using the DRV10866 motor control chip to run a small BLDC motor at about 3600 rpm. In my application once-around jitter is critical. I'm using the Fg signal as feedback in an FPGA control loop.
1. Is the Fg signal…
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 the…
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 Hi,
My customer wants to set under 200mA as overcurrent protection value. Is it problem that RCS = 18kohm? and Can we use more bigger resistor(more smaller OC value)?
Best regards, Shimizu
Part Number: DRV10866 Dear Support team
I have one question regarding DRV10866
The datasheet has very little information about the maximal and minimal frequency.
In this forum, I have out, that the range might be from 18Hz up to 680Hz.
We are planning…
Part Number: DRV10866 It can not to drive the motor to work,Please help to check it.Thanks a lot
