2-PHASE STEPPER MOTOR DRIVER
M54676P
MITSUBISHI <CONTROL / DRIVER IC>
1K
9K
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
G
Highly-accurate micro step drive by chopping sink output
transistor and source output transistor simultaneously
G
Bipolar and constant current drive
G
Built in a thermal shutdown circuit and standby circuits
G
Built in flywheel diodes
APPLICATION
Office automation equipment such as printer and FAX
FUNCTION
The M54676P can drive a stepper motor by the 2-phase bipolar
method and also controls the coil current.
Furthermore, it controls the direction of the coil current by Ph input
and the coil current value by Vref pin.
Because two control circuits are built in this IC, a stepper motor
can be driven with a single IC by the 2-phase bipolar method.
