Ordering number : EN5982A LB1847 Monolithic Digital IC PWM Current Control Type Stepping Motor Driver http://onsemi.com Overview 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 VREF voltage is constant while the current can be set in 15 steps, allowing drive of mot.
• 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 (feed-through current prevention)
• Noise canceler
• Built-in thermal shutdown circuit
• Built-in logic low-voltage OFF circuit
