NJU7329A
Single-phase DC Brushless Motor Driver IC
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
The NJU7329A is a single-phase DC brushless motor
driver IC for small fan-motor and high power applications. It
features MOS-FET driver circuit for better saturation
characteristics. Slew late of amplifiers and feedback
resistors are optimized to achieve low-noise motor
operation. The NJU7329A also includes. Frequency
generator (FG) output for various control needs.
