Overview
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.
