LB11920
Overview
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
• Three-phase bipolar drive (35V, 3.5V)
• Direct PWM drive
• Built-in high and low side kickback absorbing diodes
• Braking function (short-circuit braking)
• Built-in forward/reverse direction switching circuit
• Full complement of built-in protection circuits, including current limiter, low-voltage protection, motor lock
(physical constraint) protection, and thermal protection circuits
• The PWM duty can be controlled by IC inputs
