PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
(12). Output current timing chart under Ph inputs and I0, I1 output
conditions.
Under output current wave forms show the current that a
motor driver is going to control, so these do not show the
actual current wave forms.
