LB1929 General Description

The LB1929 is a three-phase brushless motor driver that is optimal for driving the drum and paper feed motors in laser printers and plain-paper copiers. It can provide drive with minimal power loss due to direct PWM drive technique, features on-chip peripheral circuits such as a speed control circuit and an FG amplifier, and can implement a drive circuit in a single chip.
