■GENERAL DESCRIPTION

The NJU7333 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. Maximum output current is 500mA. The NJU7333 includes. frequency generator (FG) output, lock detect (with auto recovery circuit) ,and a thermal shutdown circuit .
