TYPICAL APPLICATIONS
TYPICAL APPLICATIONS
In typical applications such as a personal computer printer, the MC34921 would supply the motor drive and control for two bi-
directional dc motors, two unidirectional dc motors, and one unipolar stepper motor. In addition, the MC34921 would supply the
power management for the printer including: the system MCU core voltage, the 3.3V logic supply, and the 5V logic supply. The
MC34921 also would supply the system with the means to read and pre-process the carriage position information from an analog
optical encoder.
