RE,
I am now having some luck with sine mode but I still have some way to go.
If you please, could you tell me how the DRV8308 does the startup?
I'm guessing that the DRV' starts in open loop PWM mode with SPEED setting the startup duty cycle. The three hall signals directly commutate the output phases.
Is this correct? Do you have a block diagram or something that shows how duty cycle is ramped or set during startup?
Thank you for your help.
