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
