TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT MULTI−CHIP TA8490F TA8490F 3−PHASE FULL WAVE BRUSHLESS DC MOTOR DRIVER IC FOR CD−ROM DRIVES This 3−phase, full−wave, brushless DC motor driver IC has been developed for use in CD−ROM drive spindle motors. The TA8490F contains in its upper stage a discrete power transistor which, thanks to its low−saturation characteristic, enables the IC to provide superior thermal efficiency. Furthermore, the multi−chip structure of this device facilitates dispersion of the heat generated inside the package, making it possible to suppress heat concentration. FEATURES l Multi−chip structure (3 RN6006 chips built−in) l 3−phase, full−wave, semi−linear drive l Current drive / current control l Built−in current limiter : ILIM = 0.6A (typ.) (at RF = 0.
