Ordering number : ENA0604 LB11921T Monolithic Digital IC Three-Phase Brushless Motor Driver http://onsemi.com Overview The LB11921T is a pre-driver IC designed for variable-speed control of 3-phase brushless motors.

It can be used to implement a motor 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 LB11921T includes a built-in VCO circuit, applications can con
