LB11920: Direct PWM Drive 3-Phase Brushless Motor Driver

The LB11920 is a direct PWM drive motor driver IC for 3-phase power brushless motors. The PWM duty can be controlled by IC inputs, and it can be used over the wide supply voltage range of 9.5 to 30V.

Features
  • Direct PWM drive
  • Built-in high and low side kickback absorbing diodes
  • Braking function (short-circuit braking)
  • Full complement of built-in protection circuits, including current limiter, low-voltage protection, motor lock (physical constraint) protection, and thermal protection circuits
  • Three-phase bipolar drive (35V, 3.5V)
  • Built-in forward/reverse direction switching circuit
  • The PWM duty can be controlled by IC inputs
Benefits
  • Easy control
  • Kickback protection
  • Safety design
  • Current limit protection
Applications
  • Consumer
