Other Parts Discussed in Thread: DRV8801

Hi,

Please let me question the control of the DRV8801.

①Quickly switch the forward and reverse rotation, yet you want to repeat the operation.
  In this case, what is the mode of operation recommended in DRV8801?

②Of when to switch rotation (forward ⇔ reverse), What is the switching time?
　(Switching delay time)

Best regards

    What do you mean "mode of operation"? If you are referring to MODE1 and MODE2, many applications set MODE1 to 1 and MODE2 to 0 for Low-side slow decay.

    The outputs typically switch in 600ns (tpd).
