... The RESET signal at Low level not only turns off the output signals but also stops the internal clock functions, while MO (Monitor Output) signals are set to low. Output signals are initiated from the initial point after release of RESET (High), as shown in Figure 2. MO signals can be used as rotation and initial signals for stable rotation checking. 7 TA8435H/HQ 2006-3-2 ...

... IC used to drive the stepping motor efficiently at low vibration. 1. Micro-step drive The TA8435H/HQ drives the stepping motor in micro steps with a maximum resolution of 1/8 of the 2-phase stepping angle (in 2W1-2-phase mode). In micro step operation, A-phase and B-phase current levels are set inside the IC so that the composite vector size and the rotation angle are even ...

... When switching between phase modes other than 2-phase, the current can be switched without fluctuation if the timing of MO output = Low. However, when switching as follows, set RESET to Low beforehand: from 1-2-phase to W1-2-phase or 2W1-2-phase mode; from W1-2-phase to 2W1-2-phase mode. <Example of Input Signal> 23 TA8435H/HQ 2006-3-2 ...

... Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. 26 TA8435H/HQ 2006-3-2 ...
