December 12, by Robert Keim This article discusses features and functionality offered by integrated circuits that simplify the task of controlling a stepper motor. In the previous article, we explored the issue of controlling a typical i.

These devices provide functionality that makes it much easier to implement a high-performance system built around a brushed DC fatasheet, and the same is true for ICs that can drive stepper motors. A typical permanent magnet stepper motor has two windings.

If the system uses a bipolar driver, rotation is achieved by applying a specific pattern of forward and reverse current through the two windings.

Thus, bipolar drive requires an H bridge for each winding. Datashret drive uses four separate drivers, and these do not need to be able to apply current in both directions: The current associated with each driver always flows in the same direction.

The first thing to keep in mind is that ICs intended for basic motor control functionality—or even just basic driver functionality—can be used with stepper motors. The generic-IC approach is convenient if you already own or have experience with a suitable driver—you can save a few dollars by reusing an old part, or you can save time and reduce the likelihood of design mistakes by incorporating a known and proven part into your stepper-controller schematic.

The downside is that a more sophisticated L2608 could provide enhanced functionality and ensure a simpler ll6208 task, and this is why I prefer a stepper driver that has additional features.

Highly integrated stepper-motor controllers can greatly reduce the amount of design effort involved in higher-performance stepper-motor applications. The first beneficial feature that comes to mind is automated step-pattern generation—i. Instead of logic inputs that directly control the current applied to the motor windings, the L has. As the name implies, microstepping causes the stepper motor to perform a rotation that is significantly smaller than one step.

Microstepping enables higher-resolution motor positioning, and it also allows for smoother rotation. In some applications, microstepping is completely unnecessary.

However, if your system might benefit from extremely precise positioning, smoother rotation, or reduced mechanical noise, you should consider a driver IC that has microstepping capability.

If you have a microcontroller for generating the step pattern and enough time and motivation to write reliable code, you can control a stepper motor with discrete FETs. I was l2608 digging through a parts junk box the other day and found an old L stepper driver chip I thought was interesting. It looks like it was made in and it is in a DIP package. This article discusses features and functionality offered by integrated circuits that simplify the task of controlling a stepper motor.
