Description
MAS9012 is a Miniature Stepper Motor Driver IC with four different versions to drive one to four motors of pointers in motorcycle and car dashboards and other similar applications.
Features
- a microstepping function to allow smooth movement of the motor shaft. One microstep corresponds to an angular rotation of 1/12 degree of the motor shaft. The actual precision of the position is affected by the gear play of the motor. The microstepping movement of the motor shaft is achieved by converting a pulse sequence into a current level sequence sent to the stepper motor coils.
