kr Ordering number : EN7109A Monolithic Digital IC LB11826 Overview For OA Products Three-Phase Brushless Motor Driver 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 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 using the LB11826 in conjunction with the Sanyo LB11825M.
Features • Three-phase bipolar drive (30V, 2.
5V) • Direct PWM drive • Built-in low side inductive kickback absorbing diode • Speed discriminator + PLL speed control • Speed locked state detection output • Built-in forward/reverse switching circuit • Full complement of built-in protection circuits, including current limiter circuit, thermal protection circuit, and motor constraint protection circuit.
