LB11923V Three-Phase Brushless Motor Driver Monolithic Digital IC Overview www.onsemi.com The LB11923V is a pre-driver IC designed for variable-speed control of 3-phase brushless motors. It can be used to implement amotor drive circuit with the desired output capacity (voltage, current) by using discrete transistors for the output stage. It implements direct PWM drive for minimal power loss. Since the LB11923V includes a built-in VCO circuit, applications can control the motor speed arbitrarily by varying the external clock frequency.
