LV8111V

www.DataSheet.co.kr Ordering number : ENA1416A Bi-CMOS IC LV8111V Overview For Polygon Mirror Motor 3-phase Brushless Motor Driver The LV8111V 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 Direct PWM drive + synchronous rectification IO max1 = 2.5A IO max1 = 3.0A (t ≤ 0.1ms) Output current control circuit PLL speed control circuit Phase lock detection output (with mask function) Compatible with Hall FG Provides a 5V regulator output Specifications Parameter Supply voltage Full complement of on-chip protection circuits, including lock protection, current limiter, under-voltage protection, and thermal shutdown protection circuits 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 Hall bias pin (Bias current cut in a stopped state) SDCC (Speed Detection Current Control) function Maximum Ratings at Ta = 25°C Symbol VCC max VG max Output current IO max1 IO max2 Allowable Power dissipation Operation temperature Storage temperature Junction temperature Pd max Topr Tstg Tj max VCC pin VG pin ...
