Capable to Drive One to Four Motors
•
Low Operating Voltage
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. It
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.
