2-PHASE STEPPER MOTOR DRIVER
M54671SP
MITSUBISHI <CONTROL / DRIVER IC>
DESCRIPTION
The M54671SP is a semiconductor IC to drive a bipolar 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
G
Built in a thermal shutdown circuit
APPLICATION
Office automation equipment such as printer, FDD, HDD, and FAX
FUNCTION
The M54671SP 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 stepping motor
can be driven with a single IC by the 2-phase bipolar method.
