LB11826中文资料LB11826: Direct PWM Drive 3-Phase Brushless Motor Driver数据手册ONSEMI规格书

描述 Description

The LB11826 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 device 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 using the LB11826 in conjunction with the LB11825M.
