TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT MULTICHIP
TA8490F
3PHASE FULL WAVE BRUSHLESS DC MOTOR DRIVER IC FOR CDROM DRIVES
This 3phase, fullwave, brushless DC motor driver IC has been
developed for use in CDROM drive spindle motors. The
TA8490F contains in its upper stage a discrete power transistor
which, thanks to its lowsaturation characteristic, enables the IC
to provide superior thermal efficiency.
Furthermore, the multichip structure of this device facilitates
dispersion of the heat generated inside the package, making it
possible to suppress heat concentration.
FEATURES
Multichip structure (3 RN6006 chips builtin)
3phase, fullwave, semilinear drive
Current drive / current control
Builtin current limiter : ILIM = 0.6A (typ.) (at RF = 0.3 )
Builtin reversing brake / short brake functions
FG signal output (using hall element output signal)
Builtin switching regulator controller
Builtin hall bias
Builtin thermal shutdown circuit
Package : MFP30
Weight : 0.63 g (typ.)
