DESCRIPTION
The M54676P is a semiconductor IC to drive a bipolar stepper motor by the micro step method by changing the coil current of the motor continuously.

FEATURES
● Highly-accurate micro step drive by chopping sink output transistor and source output transistor simultaneously
● Bipolar and constant current drive
● Built in a thermal shutdown circuit and standby circuits
● Built in flywheel diodes

APPLICATION
    Office automation equipment such as printer and FAX
