a built-in microstepping controller that implements unipolar constant current PWM drive. Since this IC includes a 4-phase distribution controller for stepping motors, it can contribute not only to system simplification but to circuit standardization as well. The STK672-060 supports the 2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase excitation (drive) methods and can control the motor with the basic stepping angle of the stepping motor divided into up to 16 divisions. Motor rotation.
