NJU7326
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.
