M54679SP 2-Phase Stepper Motor Driver REJ03F0052-0100Z Rev.1.0 Sep.17.2003 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. Function The M54679SP is a semiconductor integrated circuit, which can drive to 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 .
