General Description

The NJU7388B is a 3-phase brushless DC motor controller with 150° commutation and lead angle control functions, which provides low vibration, low noise and high efficiency motor driving. The NJU7388B generates 150° commutation 3-phase sequence based on external hall signal and arbitrary lead angle setup. It has Clock Generator for reference clock of various functions such as commutation angle, lead angle, PWM, lock protection, current detection. The NJU7388B is a 5V logic operation-specific control IC. Therefore, it corresponds to various applications by selecting Pch MOSFETs and Nch MOSFETs as power stage.
