NJU7327
Single-phase DC Brushless Motor Driver IC
I GENERAL DESCRIPTION
I PACKAGE OUTLINE
The NJU7327 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 NJU7327 also includes frequency generator
(FG) output for various control needs.
