LV8112VB: 3-phase Brushless Motor Driver for Polygon Mirror Motor
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.

- 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
