Preliminary

THREE-PHASE DC BRUSHLESS MOTOR CONTROL IC

■ GENERAL DESCRIPTION

■ PACKEGE OUTLINE

The NJW4302 is a three-phase DC brushless motor

pre-driver IC for precision applications.

The NJW4302 consists of PWM driver, motor velocity

control, FG(Frequency Generator) output, and voltage

velocity integration circuit.

The NJW4302 realizes stabilized velocity and it is suitable

for printer, FAX, and other DC motor control systems.
