LB11822 Three-Phase Brushless Motor Driver

www.DataSheet4U.com Ordering number : ENN7105 Monolithic Digital IC LB11822 Three-Phase Brushless Motor Driver for OA Products Overview The LB11822 is a three-phase brushless motor driver that is optimal for driving drum and paper feed motors in laser printers and plain paper copiers. This IC adopts a direct PWM drive technique for minimal power loss. Flexible control of motor speed in response to an externally provided clock frequency (corresponding to the FG frequency) can be implemented by.
