Overview
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.
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)
