Driving Stepper Motors with the MC1413/MC1416 (MEC163E)

This shield circuit is adapted from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. It can be used as a shield for stepper motors in mechatronics or robotics projects or as a building block for more simple projects.

The MC1413 and MC1416 ICs, from Motorola, are equivalent to the ULC2003 and can be used to drive stepper motors as shown in Figure 1. The MC1413 has an equivalent circuit for each stage, and the MC1416 has the other configuration.

The difference is that the MC1413 has characteristics that match it with TTL logic and microcontrollers, and the MC1416 with CMOS logic with voltages from 8 to 18 V. The block can control currents up to 500 mA per winding, and the maximum voltage in the motor is 50 V.
