Single-phase DC Brushless Motor Driver IC

IGENERALDESCRIPTION

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.
