M54679SP Datasheet | Hitachi Semiconductor

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 ponents. (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.
