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.
