3-phase Brushless Motor Driver

for Polygon Mirror Motor

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

SSOP44K(275mil) Exposed Pad

 Direct PWM drive + synchronous rectification

 I max1 = 2.5A

 I 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)
