DATA SHEET
LB11946
Overview
PWM Current Control Stepping
Motor Driver
Monolithic Digital IC
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
鈥?PWM current control (with a fixed off time)
鈥?Logic input serial-parallel converter (allows 1-2, W1-2, 2W1-2, and 4W1-2 phase excitation drive)
鈥?Current attenuation switching function (with slow decay, fast decay, and mixed decay modes)
鈥?Built-in upper and lower side diodes
鈥?Simultaneous on state prevention function (through current prevention)
鈥?Noise canceller function
鈥?Thermal shutdown circuit
鈥?Shutoff on low logic system voltage circuit
鈥?Low-power mode control pin
