Description
The M54679FP is a semiconductor integrated circuit designed for stepper motor driver used to Printer, PPC and
Facsimile.
Features
•
Wide supply voltage sphere (10 – 35V).
•
Bipolar, constant current PWM function.
•
(Top side transistors PWM function, maximum current is 0.8 Amps).
•
Few external components.
(This IC can be operated with 1 capacitor and 2 resistances).
•
4 phases input style (include the protection function of output through current).
•
Output current change function (2 bits, 4 type currents).
•
Thermal protection circuit.
•
Include flywheel diodes.
Application
Printer, PPC and Facsimile.
Function
The M54679FP is a semiconductor integrated circuit which can drive two phase stepper motor.
It can control the direction of motor current and output motor current (4 steps) by I0, I1 terminals.
Also, it can drive the two phase bipolar stepper motor by one IC as it include two current control circuits.
