Power supply for the actuator
driver controller, maximum value
circuit for PWM, and sled
controller.
Base drive output pin for the
external NPN-Tr for the battery
pulse charging circuit.
Base drive output pin for the
external step-down NPN-Tr used
when external voltage input is
applied.
Base drive output pin for the
PNP-Tr for the step-down PWM
that generates the power supply
for the H bridge driver that drives
the focus/tracking group
actuators. (Open when there is
one H bridge power supply.)
Base drive output pin for the
PNP-Tr for the step-down PWM
that generates the power supply
for the H bridge driver that drives
the spindle/sled group actuators.
(DNB-2 becomes the drive pin
when there is one H bridge
power supply.)
Base drive output pin for the
external NPN-Tr for the step-up
circuit that sets the external
voltage for the DSP.
