http://onsemi.com
Overview
The LV8746V is a stepper motor driver corresponding to the Quarter-step excitation drive that the selection of CLK-IN input and a parallel input is possible. It is ideally suited for driving stepper motors used in office equipment and amusement applications.
Function
• PWM current control stepper motor driver incorporated. • BiCDMOS process IC • Low on resistance (upper side : 0.84Ω ; lower side : 0.7Ω ; total of upper and lower : 1.54Ω ; Ta = 25°C, IO = 1A) • Excitation mode can be set to Full-step, Half-step Full torque, Half-step, or Quarter-step • CLK-IN input and a parallel input can be selected.
