  • 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 - Low consumption
  • PLL speed control circuit - High efficiency and Low jitter
  • Current limiter, constraint protection, thermal shutdown, under-voltage protection circuit - Safety design
  • 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
  • Compatible with Hall FG
  • Hall bias pin (Bias current cut in a stopped state)
  • 5V regulator output
  • SDCC function (Speed Detection Current Control)
  • Applications
  • Polygon Mirror motor
  • End Products
  • Laser beam printer (LBP)
  • Plain paper copier (PPC)
  • Multi function printer (MFP)
