Description
The M54679SP is a semiconductor integrated circuit that can drive the bipolar stepping motor directly by controlling the coil-current at low level.

FEATUREs
• Wide supply voltage sphere (10 to 35 V)
• Bipolar, constant current PWM function.
    (Topside 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 charge function (2 bits, 4 type currents).
• Thermal protection circuit.
• Include flywheel diodes.

APPLICATION
• Printer, PPC and Facsimile.
