LB11876: Three-Phase Brushless Motor Driver
The LB11876 is a 3-phase brushless motor driver developed for driving the polygonal mirror motor in plain-paper copiers and similar products. It can support any motor voltage and motor current required by the use of appropriate external components. The LB11876 adopts direct PWM drive to achieve drive with minimal power loss. This is a version of the LB11875 with a modified constraint protection function.
特性- Three-phase bipolar drive (direct PWM)
- PLL speed control circuit
- Dedicated external clock
- Clock divider switching function
- Hall sensor FG support
- Short-circuit braking function
- Built-in current limiter, thermal protection, constraint protection, and undervoltage protection circuits
