3 Description
TPIC2010 is a very-low noise type motor driver IC
suitable for slim or ultra-slim ODD. The 9-channel
driver IC controlled by serial I/F is optimal for driving
a spindle motor, a sled motor (stepping motor
applicable), a load motor, and focus / tracking / tilt
actuators and stepping motor for collimator lens. This
driver IC includes 2-channel synchronous DC-DC
converters.
