NJM2624A
BRUSH LESS DC MOTOR PRE-DRIVER
■GENERAL DESRIPTION
■PACHAGE OUTLINE
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.

TYPICAL APPLICATION
• A rotation direction change must be made after motor stopped completely.
• When PWM duty is extremely small, two or more switching elements can not be driven entirely.
In such case, switching elements will generate excess heat and it may cause destruction of the
switching devices. Therefore, extensive heat evaluation is necessary for switching device selection
particularly in consideration of the area of safety operation (ASO).
