LV8111VB: 3-phase Brushless Motor Driver for a Polygon Mirror Motor

The LV8111VB is a 3-phase brushless motor driver intended as a fully integrated driver for a laser beam printer (LBP) polygon mirror motor. This is a highly integrated solution which uses a DMOS output structure and employs synchronous rectification for low power consumption and a phase locked loop (PLL) speed control scheme to achieve extremely high rotational precision.

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
  • Compatible with Hall FG
  • Hall bias pin (Bias current cut in a stopped state)
  • 5V regulator output
  • SDCC function (Speed Detection Current Control)
Benefits
  • Low consumption
  • High efficiency and Low jitter
  • Safety design
Applications
  • Polygon Mirror Motor
End Products
  • Laser beam printer (LBP)
  • Plain paper copier (PPC)
  • Multi function printer (MFP)
