Spindle Motor and 5ch Actuator Driver
REJ03F0024-0100Z
Rev.1.0
Sep.16.2003
Features
This IC is 1 chip driver IC for spindle motor and 5 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 four voltage supply terminals (for Spindle, Slide,Focus/Tracking and Loading), and four voltage supply can
be set separately.
Further more this IC has short braking select function, FG amplifier, thermal shut down circuit, standby circuit, reverse
rotation detect circuit.
