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.
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 slow decay, fast decay, and mixed decay modes)
Integrated upper and lower side diodes
