For EVAL6229 or EVAL6235 with PractiSpin board it looks like 3.3V or 5V reference is from other PCB, is there a way for L6229 or L6235 to supply 5V (for EN, F/R, BRAKE) internally?

Does ST make compatible 8-52V to 5V (or 3.3V) DC-DC conveter that would be good companion for L6229 if this cannot make own 5V source (like L4971 but with fixed output and not needing so many external components?)

The EVAL boards can generate the 5V pull-up voltage through a zener diode.

For your final application ST proposes a wide range of step-down converters covering the 8V to 52V range. For example you can use the
