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.
