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.

• 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.
