Overview
The LV8712T is a stepping motor driver of the micro-step drive corresponding to supports 2W 1-2 phase excitation. It
is the best for the drive of the stepping motor for a scanner and a small printer.
Features
Single-channel PWM constant-current control stepping motor driver incorporated.
Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 2W1-2 phase
Microstep can control easily by the CLK-IN input.
