1 (9) 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 positi on 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. FEATURES APPLICATIONS

  • Bipolar Stepper Motor Driver Outputs
  • Drives One to Four Stepper Motors
  • Microstepping Function
  • Glitch Filters at All Inputs
  • Low Operating Voltage
  • TSSOP-28 Package
  • Motorcycle Dashboards
  • Car Dashboards
  • Nautical Instrumentation
  • Miniature Stepper Motors in Appliances This is preliminary information on a new product under development. Micro Analog Systems Oy reserves the right to make any changes without notice.
