Part Number: DRV10964 Tool/software: Hi -
Customer is using the DRV10964 on new design. Currently working on PI control loop on the MCU control.
What is the most common control frequency of the control loop? Once per cycle? Multiple times per cycle?

Looking for FG pin functionality clarification.
During normal closed-loop operation, does FG pin give immediate feedback on rotation speed? Or does it give "target speed" feedback?
Consider a load impulse…

Hi Thomas,
Open loop run is not reliable always and not efficient. Close Loop can monitor for motor stall state.
For such applications it will be better to use DRV10975, DRV10983Q1, MCF8315A/C etc. In this we will program the parameters (R, L, KE) to…
Hi Jens van zon,
DRV10964 measures Rm and Kt during startup and we cannot program this. Please ignore my explanation about programming Kt/Rm as this is not applicable for this device.
Hand off speed is determined through experiment. The higher speed motors…

Hi Jimmy Wang,
Please confirm if this data sheet information clarifies that Duty should be > 0% and less than 100% . Device requires an edge transition.
Thanks and Best Regards,

Part Number: DRV10964 It is my understanding that the DRV10964 does not have a common pin.
How should the common be handled when rotating a motor with a common? Is there a virtual COM inside the IC?
