... TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6560HQ,TB6560FG PWM Chopper-Type bipolar Stepping Motor Driver IC The TB6560HQ/ PWM chopper-type sinusoidal micro-step bipolar stepping motor driver IC. It supports both 2-phase/1-2-phase/W1-2-phase/2W1-2-phase excitation mode and forward/reverse mode and is capable of low-vibration, high-performance drive of 2-phase bipolar type stepping motors using only a clock signal ...

... It is recommended that M1 and M2 signals be changed after setting the RESET signal Low during the Initial state (MO is Low). Even when the MO is Low, changing the RESET signal without setting the RESET signal Low may cause the discontinuity in the current waveform. TB6560HQ/FG W1-2-phase excitation 13 ...
