MI-Bus Interface Stepper
Motor Controller
The MC33192 Stepper Motor Controller is intended to control loads in
harsh automotive environments using a serial communication bus. The
MI–Bus can provide satisfactory real time control of up to eight stepper
motors. MI–Bus technology offers a noise immune system solution for
difficult control applications involving relay drivers, motor controllers, etc.
The MC33192 stepper motor controller provides four phase signals to
drive two phase motors in either half or full step modes. When used with an
appropriate Motorola HCMOS microprocessor it provides an economical
solution for applications requiring a minimum amount of wiring and optimized
system versatility.
The MC33192 is packaged in an economical 16 pin surface mount
package and specified at an operating voltage 12 V for – 40°C ≤ TA ≤ 100°C.
