General Description
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 systems and protection circuits such as a lock protection, auto-recovery circuit and thermal shutdown useful for high-current applications.The NJU7329B is available in a small and thin surface mount package of MSOP10 (TVSP10), which proves downsizing and thinning in motor applications.
