LB1928 Datasheet | SANYO

.. Ordering number : ENN6198A Monolithic Digital IC Three-Phase Brushless Motor Driver for Office Automation Equipment Overview The LB1928 is a 3-phase brushless motor driver well suited for drum and paper feed motors in laser printers, plain-paper copiers and other office automation equipment. Direct PWM drive allows control with low power losses. Peripheral circuitry including speed control circuit and FG amplifier is integrated, thus allows drive circuit to be constructed with a single chip.
