Notes
Input terminal system [RESET Clock (timing input signal upon rising power supply)] driver configured include system logic section MOSFETs section. MOSFETs both VCC1 side side N-channels. Thus, MOSFETs VCC1 side provided with charging pump circuit generating voltage higher than that VCC1. When signal input RESET terminal operating RESET, charging pump stopped. After release RESET (High input), requires period 1.7ms rise charging pump. Accordingly, even when Clock signal input during rising charging pump circuit, MOSFET cannot operated. Such timing needs taken into consideration inputting Clock signal. example timing shown Figure

Refer timing charts operations. [Clock] Clock signals should input under following conditions that types excitation modes shown Excitation Mode Table. Input frequency range 50kHz Minimum pulse width High level duty When Mode used, operation based rising Clock thus above-mentioned condition high level duty negligible. minimum pulse width more allows excitation operation Mode Mode Since operation based rising falling Clock under Mode most preferable high level duty obtain uniform step-wise current widths. [Mode Mode Mode These terminals allow selection excitation modes. specific operations, refer Excitation Mode Table Timing Charts.

[Hold, CW/CCW] Hold temporary holds motor while phase current motor conducted, even when there clock inputs input. High input releases hold, motor current changes again synchronizing with rising Clock signals. Refer Timing Chart exemplary operations. CW/CCW switches rotational direction motor. Switching High gives rotational operation gives rotation operation CCW. timing switching rotation synchronizes rising clock signals. Refer Timing Chart exemplary operations. [Enable] High input renders normal operation input forcibly renders gate signal MOSFETs Low, thereby cutting motor current. Once again High input renders current conduct motor. timing current does synchronize with clock. Since input Enable forcibly cuts motor current, used V-phase W-phase while Clock maintained level state after RESET operation.
