3-phase Brushless Motor Driver for Polygon Mirror Motor
.onsemi.
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 posed of a single-chip. Also, the output transistor is made DMOS by using Bi DC process, and by adopting the synchronous rectification method, the lower power consumption (Heat generation) is achieved.

- 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
- patible with Hall FG
- Hall bias pin (Bias current cut in a stopped state)
