LB11922: Three-Phase Brushless Motor Driver
The LB11922 is a pre-driver IC designed for constantspeed control of 3-phase brushless motors. It can be used to implement a motor drive circuit with the desired output capacity (voltage, current) by using discrete transistors for the output stage. It implements direct PWM drive for minimal power loss.
Features- Direct PWM drive output
- Speed discriminator + PLL speed control circuit
- Speed lock detection output
- Built-in crystal oscillator circuit
- Forward/reverse switching circuit
- Braking circuit (short braking)
- Full complement of on-chip protection circuits, including lock protection, current limiter, and thermal shutdown protection circuits.
