NJU7346

NJU7346 Single-phase DC Brushless Motor Driver IC ■ GENERALDESCRIPTION ■ PACKAGE OUTLINE The NJU7346 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. It has a FG (frequency generator) output useful for various control systems and thermal NJU7346R shutdown circuit useful for high-current applications. Further it ( MSOP10 (VSP10) ) incorporates feed-back resistances to provide optimized output wave for low noise motor driving. The NJU7346 is available in a small and thin surface mount package of MSOP10 (TVSP10), which provides downsizing and thinning in motor applications. ■ FEATURES Operating Voltage 3.5 to 14V Frequency Generator Output Thermal Shutdown Circuit Low Operating Current Low Saturation Output Voltage Vsa...
