Description
The M54678FP is a semiconductor integrated circuit designed for stepper motor driver used to printer, PPC and
facsimile.
Features
• Wide supply voltage range (10 – 35V)
• Output current is controlled by PWM operation
• Few external components (This IC can be operated with 1 capacitor and 2 resistances)
• Voltage stabilizer circuit (Regout = 3.5V)
• Thermal protection circuit
• 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.
