LV8746V
Overview
LV8746V is 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of
micro-step drive and supports Full-step, Half-step (full torque), Half-step, and Quarter-step resolution, which
can select the CLK-IN input and the parallel input. This is best suited for driving of the stepping motor for OA
and amusement.
