Freescale has an interesting product line: embedded MCU plus power, MM908Exxx. It is a combination of analog features such as high side and low side switches, H-bridge stepper motor drivers using SMARTMOS technologies with Freescale standard flash microcontroller (HC08/HC12) in a single package.

The Motor Control Development System provides the application developer with the assistance of quick prototyping and validation of motor control applications.

The majority of modern printers use steppermotors and solenoids for driving the various transport and print mechanisms. These applications usually involve using drive signals directly from the control logic; and handling high-pulsed currents and voltages.

How a motor driver which we use in our microcontroller circuits for the purpose of driving motors, i.e. L293D (datasheet)
