LV8111VB Bi-CMOS LSI 3-phase Brushless Motor Driver for Polygon Mirror Motor www.onsemi.com Overview The LV8111VB 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. Feature  3-phase bipolar drive  Direct PWM drive + synchronous rectification  IO max1 = 2.5A  IO max2 = 3.0A (t  0.1ms)  Output current control circuit  PLL speed control circuit  Phase lock detection output (with mask function)  Current limiter, constraint protection, thermal shutdown, under-voltage protection circuit  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) Typical Applications  Laser beam printer (LBP)  Plain paper copier (PPC)  Multi function printer (MFP) SSOP44K(275mil) Exposed Pad ORDERING INFORMATION See detailed ordering and shipping information on page 15 of this data sheet. © Semiconductor Components Industries, LLC, 2014 December 2014 - Rev. 1 1 Publication Order Number : LV8111VB/D LV8111VB Specifi...
