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.
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
• Low-power mode control pinApplications
• PWM current control stepping motor drivers
Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
