TA8493F/AF/BF
Toshiba Bipolar Linear Integrated Circuit Multi-Chip
TA8493F, TA8493AF, TA8493BF
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.
