LB1946
Overview
The LB1946 is stepping motor drive 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 supports for microstepping drive from 1-2 phase
excitation 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.
Applications
PWM current control stepping motor drivers
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 output diodes
Simultaneous on state prevention function (through current prevention)
Noise canceller function
Thermal shutdown circuit
Shutoff on low logic system voltage circuit
