Monolithic Digital IC
PWM Current Control Stepping Motor Driver
Overview
The LB11946 is a stepping motor driver IC that implements PWM current control bipolar drive with a fixed off time. This IC 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)
