LV8712T/LV8713T
Overview
The LV8712T and LV8713T are micro-stepping motor drivers with built-in translator for easy operation.
The LV8712T supports full-step, half-step, quarter-step, and 1/8-step resolution. The LV8713T supports
full-step, half-step, 1/16-step, and 1/32-step resolution. These ICs are optimal for driving stepping motor of
scanner and small printer.
Function
Single-channel PWM constant-current control stepping motor driver incorporated.
Microstepping is configurable to the following modes:
Full-step, half-step, quarter-step, or 1/8-step. (LV8712T)
Full-step, half-step, 1/16-step, or 1/32-step. (LV8713T)
CLK-IN input facilitates the control of microstepping.
