SPINDLE MOTOR AND 4CH ACTUATOR DRIVER
PIN CONFIGURATION This IC is 1 chip driver IC for spindle motor and 4 channel actuators. All of the motor and actuator of optical disk drive system (CD-ROM etc.) can be drived by only this IC. This IC has a direct PWM control system for Spindle and Slide channels drive due to reducing IC power dissipation. This IC has three voltage supply terminals (for Spindle, Slide/Loading and Focus/Tracking) , and these voltage supply can be set separately. Further more this IC has FG amplifier, thermal shut down circuit, standby circuit, channel select function, reverse rotation detect circuit. LOIN+ MU1 MU2 VM23 LO+ LOGND RSL SL+ SLGND W V
