LB11946 is a PWM current control stepper motor driver that implements PWM control bipolar drive with a fixed off time. It features 15 current setting levels using a fixed VREF voltage and support for micro-stepping drive from 1-2 phase excitation drive to 4W1-2 phase excitation drive. This device is optimal for driving stepper motors such as those used for carriage drive and paper feed in printers.
