In both the TTL and CMOS circuits, the stepper motor itself can be operated from a supply voltage that is wholly different from the voltage supplied to the ICs. It should be pointed out that stepper motor translator circuits are excellent first microcontroller applications. Along with providing an intelligent approach to controlling stepper motors, small microcontrollers can cost as little as $0.50 probably less than the cost of one chip used in the circuits shown in Fig. 21-8 and 21-9 and much easier to wire into a circuit.

Four NPN power transistors, four resistors, and a handful of diodes are all the translator circuits described in the last section need to provide driving power. (You can also use this scheme to increase the driving power of the UCN5804, detailed earlier.) The schematic for the circuit is shown in Fig. 21-10 (refer to the parts list in Table 21-4). Note that you can substitute the bipolar transistors and resistors with power MOSFETs. See 19, Choosing the Right Motor, for more information on using power MOSFETs.

You can use just about any NPN power transistor that will handle the motor. The TIP31 is a good choice for applications that require up to 1 A of current. Use the 2N3055 for heavier-duty motors. Mount the drive transistors on a suitable heat sink. You must insert a bias resistor in series between the outputs of the translation circuit and the base of the transistors. Values between about 1K and 3K should work with most motors and most transistors. Experiment until you find the value that works without causing the flipflop chips to overheat. You can also apply Ohm s law, figuring in the current draw of the motor and the gain of the transistor, to accurately find the correct value of the resistor. If this is new to you, see Appendix A, Further Reading, for a list of books on electronic design and theory. It is sometimes helpful to see a visual representation of the stepping sequence. Adding an LED and current-limiting resistor in parallel with the outputs provides just such a visual indication. See Fig. 21-11 for a wiring diagram (refer to the parts list in Table 21-5). Note the special wiring to the flip-flop outputs. This provides a better visual indication of the stepping action than hooking up the LEDs in the same order as the motor phases.
