Dear NXP,


first of all, our customer want to use stepper motor controller which equipped with SSD feature.

and I know that  S12ZVH/S12XHY MCU has internal SSD feature. but, these MCUs are too heavy for their application.

my question is,

is it possible to implement a similar SSD feature with  Stepper motor driver IC(e.g, MC33932/MC34932) and general S12 MCU?

I think that motor driver IC's FB(current sensing - feedback) signal can be used for this purpose.

do you have any Idea?
