The actuator control signals corresponding to
IN1: focus, IN2: tracking, IN3: spindle, IN4:
sled. Input from the ASP (DSP).
Focus coil actuator drive output
Tracking coil actuator drive output
Spindle motor drive output
Sled motor drive output
(Each channel includes built-in spark killer
diodes.)
Power supply for the four H bridge driver
channels. An external PWM step-up circuit
can be used to generate a voltage slightly
higher than the maximum voltage output by
any of the four output channels.
Input for the 3.9 V step-up circuit. The drive
control system operates on this voltage. This
voltage can also be supplied to other ICs in
the system, such as the DSP and the
microprocessor.
Input for muting of the four actuator channels
at the same time.
High: mute applied.
Threshold input used when operating the
sled motor in step drive mode.
Input that selects sled motor step drive
mode.
High: V-type selected
Low: Step mode
Dedicated ground connection for the internal
reference voltage for laser diode APC
control.
Connect to a ground near the laser diode.
