Overview
Three-Phase Brushless Motor Driver for 24 V Fan Motors
The LB11693 reduces motor noise by imparting a slope to the output current when switching the phase to which power is applied.
This motor driver includes an automatic recovery constraint protection circuit and is optimal for driving 24 V fan motors.
