For Polygon Mirror Motor
3-phase Brushless Motor Driver
Overview
The LV8112V 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.
Features
• 3-phase bipolar drive
• Full complement of on-chip protection circuits, including lock
• Direct PWM drive + synchronous rectification
protection, current limiter, under-voltage protection, and thermal
• IO max1 = 2.5A
shutdown protection circuits
• IO max1 = 3.0A (t ≤ 0.1ms)
• Output current control circuit
• Circuit to switch slowing down method while stopped
(Free run or Short-circuit brake)
• PLL speed control circuit
• Constraint protection detection signal switching circuit (FG or LD)
• Phase lock detection output (with mask function) • Forward / Reverse switching circuit
• Compatible with Hall FG
• Hall bias pin (Bias current cut in a stopped state)
• Provides a 5V regulator output
• SDCC (Speed Detection Current Control) function
