Spindle Motor AND 4CH ACTUATOR Drive IC
[FEATURES]
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 driven by only this IC.
This IC has current control drive system for Focus,
Tracking, Spindle and Slide channel drive, also 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 three voltage
supply can be set separately.
Further more this IC has an operational amplifier for Slide
input, FG amplifier, thermal shut down circuit, standby
circuit, channel SELECT function,reverse rotation detect
circuit and Short braking SELECT.
