MAS6012

Stepper Motor Driver IC

• Supports Microstepping Movement

• Capable to Drive One to Four Motors

• Low Operating Voltage

DESCRIPTION

MAS6012 is a miniature stepper motor driver IC to

drive up to four stepper motors. Applications include

motorcycle and car dashboards and miniature

stepper motor appliances. MAS6012 features a

microstepping function to allow smooth movement

of the motor shaft. Full rotor revolution consists of

24 microsteps each having 15 degree angular

rotation. With gear reduction of 180 the 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.
