LB11920
Three-Phase Brushless Motor Driver
for Office Equipment Applications
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 30 V.
Functions and Features
• Three-phase bipolar drive (35 V, 3.5 A)
• 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
