LV8111VB: 3-phase Brushless Motor Driver for a Polygon Mirror Motor
Product Description
The LV8111VB is a 3-phase brushless motor driver intended as a fully integrated driver for a laser beam printer (LBP) polygon mirror motor. This is a highly integrated solution which uses a DMOS output structure and employs synchronous rectification for low power consumption and a phase locked loop (PLL) speed control scheme to achieve extremely high rotational precision.
