2-PHASE STEPPER MOTOR DRIVER
M54672SP
MITSUBISHI <CONTROL / DRIVER IC>
DESCRIPTION
The M54672SP is a semiconductor IC to drive a stepper motor
directly by controlling the coil current with the constant current
method.
FEATURES
G
Wide output current control range (20 – 1200mA)
G
Bipolar and constant current drive
G
Built in a thermal shutdown circuit
G
Built in flywheel diodes
APPLICATION
Office automation equipment such as printer, FDD, HDD and FAX
FUNCTION
The M54672SP can drive a stepper motor by the 2-phase bipolar
method and also control the coil current. Furthermore, it controls
the direction of the coil current with Ph input pins (pins 16 and 17)
and the coil current value with V
R
pins (pins 3 and 30).
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.
