LB11826: Direct PWM Drive 3-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 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.
Features- Three-phase bipolar drive (30 V, 2.5 V)
- Direct PWM drive
- Speed discriminator + PLL speed control
- Built-in low side inductive kickback absorbing diode
- 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
