NJW4303  
PWM 3-PHASE DC BRUSHLESS MOTOR CONTROLLER  
„GENERAL DESCRIPTION  
„PACKAGE OUTLINE  
The NJW4303 is a 3-Phase Brushless DC Motor Control  
pre-driver IC with PWM control. It generates the most optimal  
current flow patterns by receiving rotor magnetic pole detection  
signals from hall elements of 3-phase brushless motor.  
Operational voltage range for the IC has margin as 9.0V to  
35V(maximum voltage of 40V), and it fits for a 12V/24V power  
supply. It is possible to put practical use such as speed control by  
internal oscillation circuit, and torque limiter control by current  
sensory circuit. With NJW4303, high reliability of various motor  
drive controls can be realized by a variety of function and a  
substantial protection circuit.
