BRUSH LESS DC MOTOR PRE-DRIVER
■GENERAL DESRIPTION ■PACHAGE OUTLINE
■FEATURES
■PIN CONFIGRATION
NJM2624A
The
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.
