PWM Current Control Type Stepping Motor Driver
Monolithic Digital IC
The LB1847 is a driver IC for stepping motors with
PWM current control bipolar drive (fixed OFF
time). A special feature of this IC is that V
REF
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 high-
precision control and low vibrations are required.
