2-PHASE STEPPER MOTOR DRIVER
M54677FP
MITSUBISHI <CONTROL / DRIVER IC>
DESCRIPTION
The M54677FP 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 – 1000mA)
G
Bipolar and constant current
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 M54677FP 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 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.
