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
