Hello there,
I am developing a segway (a stand-up bike) and currently bump into some problem.
I am using two sets of 24V BLDC hub motor, 3 phase with 3 hall sensor. Using DRV8307 to drive it.
Here is the demo video

As you can see, my current problem is that, when I switch direction, which is turning DIR pin on or off, it need about 1 second to actually turn.
I try to use brake function however the motor stuck and lock down when the braking time exceed 20ms. If I set within 20ms, it still need 1 second to make the turn.
It is way to slow for segway.
My question comes to:
Is DRV8307 or 8308 suitable for fast-switching application such as segway? If so, kindly give me some comment? it means a lot.
Cheers
