Should I be concerned? Is there a way to add the chip protection to older designs?

No way to add chip protection to the older 4UAPC boards. It is for open or shorted stepper coils only. Nothing to do about voltage.
42VDC absolute MAX...be careful of line voltage voltage variances! NOT much more speed than 36VDC.
