Number of motor revolution can be controlled by the frequency of external clock input.
4 types of modes, i. e. , 2, 2-3, W2-3 and 2W2-3-phase excitations, are available which can be selected based on rising
of clock signals, by switching highs and lows of Mode A and Mode B terminals.
Setting a Mode C terminal low allows an excitation mode that is based on rising and falling of a clock signal. By setting the Mode C terminal low, phases that are set only by Mode A and M.

semi.com Overview The STK673-011-E is a 3-phase stepping motor driver hybrid IC with built-in microstep controller having a bipolar constant current PWM system, in which a power MOSFET is employed at an output stage. It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit. The number of motor revolution can be controlled by the frequency of external clock input. 2, 2-3, W2-3 and 2W2-3phase excitation modes are available.
