Part #: LM621EN Description: IC,MOTOR CONTROLLER,BIPOLAR,DIP,18PIN Brushless motor commutator – The LM621 is a bipolar IC designed for communication of brushless DC motors.  The part is compatible with both three and four phase motors.  It can directly drive the power switching devices used to drive the motor.  The LM621 provides an adjustable dead-time circuit to eliminate “shoot-through” current spiking in the power switching circuitry.  Operation is from a 5V supply, but output swings of up to 40V are accommodated.  The part is packaged in an 18-pin, dual line package.
