LB11946 - PWM Current Control Stepping Motor Driver

Features

  • 15 current setting levels using a fixed VREF voltage and support for microstepping drive from 1-2 phase excitation drive to 4W1-2 phase excitation drive. This device is optimal for driving stepping motors such as those used for carriage drive and paper feed in printers. Features.
  • PWM current control (with a fixed off time).
  • Logic input serial-parallel converter (allows 1-2, W1-2, 2W1-2, and 4W1-2 phase excitation drive).
  • Current attenuation switching function (with sl.
