| NJM2624A BRUSH LESS DC MOTOR PRE-DRIVER sGENERAL DESRIPTION The NJM2624A is a 3-phase brushless DC motor pre-driver which requires external power-transistors suited to drive current of the motor. The Run Enable function is used as PWM control besides of ON/OFF switched function. sPACHAGE OUTLINE NJM2624AD NJM2624AM sFEATURES qOperating Voltage qLow Operating Current qRun Enable qForward or Reverse Direction qOutput Switch Current qBipolar Technology qPackage Outline NJM2624AV (V+=4.5V to 18V) (10mA max.)
