LB11946
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 micro-stepping 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 slow decay, fast decay, and mixed decay modes)
Built-in upper and lower side diodes
Simultaneous on state prevention function (through current prevention)
Noise canceller function
Thermal shutdown circuit
Shutoff on low logic system voltage circuit
Low-power mode control pin
