Single-phase DC Brushless Motor Driver IC

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJU7326 is a single-phase DC brushless motor driver IC.

It features MOS-FET output for better saturation characteristics.

Slew rate of amplifiers and feedback resistors are optimized to

achieve low-noise motor operation.

It is suitable for small fan-motor applications.
