In summary, until recently the design of a stepper motor was a fairly complex task. Thanks to the EasySPIN and dSPIN, this is task is greatly simplified. At this time no competitor has similar features, and ST EasySPIN and dSPIN are state of the art stepper motor drivers. In current mode control, the decay is automatically managed and the microstepping can contain up to sixteen microsteps. In voltage mode control, only offered by STMicroelectronics, a true 128 microsteps is achievable. In addition, the speed profile can be generated, plus the STMicroelectronics solution decreases the number of components. All this combines to make the design of high performance stepper motor easy.
