LB11847
Overview
The LB11847 is a driver IC for stepping motors with PWM current control bipolar drive (fixed OFF time). A special
feature of this IC is that VREF voltage is constant while the current can be set in 15 steps, allowing drive of motors ranging
from 1-2 phase exciter types to 4W 1-2 phase exciter types. The current decay pattern can also be selected (SLOW
DECAY, FAST DECAY, MIX DECAY) to increase the decay of regenerative current at chopping OFF, thereby
improving response characteristics. This is especially useful for carriage and paper feed stepping motors in printers and
similar applications where highprecision control and low vibrations are required.
Features
PWM current control (fixed OFF time)
Load current digital selector (1-2, W1-2, 2W1-2, 4W1-2 phase exciter drive possible)
Selectable current decay pattern (SLOW DECAY, FAST DECAY, MIX DECAY)
Simultaneous ON prevention function (feedthrough current prevention)
Noise canceler
Built-in thermal shutdown circuit
Built-in logic low-voltage OFF circuit
