3-Phase Full Wave Brushless DC Motor Driver IC for CD-ROM Drives
These 3-phase, full-wave, brushless DC motor driver ICs have
been developed for use in CD-ROM drive spindle motors. The
TA8493F/ AF/ BF contain in its upper stage a discrete power
transistor (P-ch-MOS) and uses direct PWM control system,
which 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.
