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.
