LV8746V: PWM Constant-Current Control Stepper Motor Driver

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.

Features
  • 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
  • Motor current selectable in four steps
  • Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated
  • CLK-IN input and a parallel input can be selected
  • PWM current control stepper motor driver incorporated.
  • BiCDMOS process IC
  • CLK-IN input and a parallel input can be selected.
  • Unusual condition warning output pins
  • No control power supply required
