DRV8805 Excitation Procedure

Dear, Sir.

My customer is interested in DRV8805 as Unipolar stepper motor driver.

The excitation procedure for full-step, half-step, wave drive is described on page

10 & 11 on the datasheet.

Typical application schematic is also described on page 12.

They pointed out the strange point of the excitation based on the schematic.

I also checked ;

It should be OUT2=>OUT3, OUT3=>OUT2, I suppose.

Is it a kind of miss-typing or another reason the excitation procedure looks strange?

Best Regards,

H. Sakai
