MC33030 schematic block diagram and typical position servo application

MC33030 produced by MOTOROLA is a single-chip dedicated integrated circuit suitable for closed-loop position control
and speed control of micro DC servo motors . It includes a complete circuit from the error amplifier and reference input terminal that receives the feedback input signal to the final H-bridge power amplifier, over-current and over-voltage protection. Only a few peripheral components can constitute the entire system and realize Four-quadrant switch control of DC servo motor .
