3 Description
The TPIC2060A is a low-noise motor driver IC
suitable for 12-V ODD. The 9-channel driver IC
controlled by a serial interface is optimized for driving
a spindle motor, a sled motor (stepping motor
applicable), a load motor, focus / tracking / tilt
actuators, and stepping motor for collimator lens.
