LV8112VB: 3-phase Brushless Motor Driver for Polygon Mirror Motor

The LV8112VB is a 3-phase brushless motor driver for polygon mirror motor driving of LBP. A circuit needed to drive of polygon mirror motor can be composed of a single-chip. Also, the output transistor is made DMOS by using BiDC process, and by adopting the synchronous rectification method, the lower power consumption (Heat generation) is achieved.

Features
  • Direct PWM drive + synchronous rectification
  • PLL speed control circuit
  • Current limiter, constraint protection, thermal shutdown, under-voltage protection circuit
  • 3-phase bipolar drive
  • IO max1 = 2.5A
  • IO max2 = 3.0A (t is within 0.1ms)
  • Output current control circuit
  • Phase lock detection output(with mask function)
  • Circuit to switch slowing down method while stopped(Free run or Short-circuit brake)
  • Constraint protection detection signal switching circuit (FG or LD)
  • Forward / Reverse switching circuit
