NJU7329B - JRC

NJU7329B Single-phase DC Brushless Motor Driver IC

The NJU7329B is a single-phase DC brushless motor driver IC designed for small and high power fan-motor applications. It provides a low operating current of 3mA (typ.) and low saturation output voltage at high output current operation, which offers a high efficiency motor driving. Further it has a frequency generator (FG) output useful for various control sy.
