2-PHASE STEPPER MOTOR DRIVER
M54678FP
MITSUBISHI <CONTROL / DRIVER IC>
PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
The M54678FP is a semiconductor integrated circuit designed for
stepper motor driver used to printer, PPC and facsimile.
FEATURES
G
Wide supply voltage range (10 – 35V)
G
Output current is controlled by PWM operation
G
Few external components (This IC can be operated with 1
capacitor and 2 resistances)
G
Voltage stabilizer circuit (Regout = 3.5V)
G
Thermal protection circuit
G
Flywheel diode
APPLICATION
Printers, PPC, facsimile
FUNCTION
The M54678FP is a integrated circuit which can drive two phase
stepper motor. The output current direction is determined by phase
terminal function, and the output current level is controlled by Vref
terminals voltage.
