TPIC2030 - Texas Instruments

TPIC2030 Serial I/F Controlled 7-Channel Motor-Driver

TPIC2030 is very-low noise type motor driver IC suitable for slim or ultra-slim DVD reader/writer. The integrated current sense resistance for the spindle motor reduces cost and board area in designs. The TPIC2030 is an integrated solution for driving the spindle motor, sled motor, load motor, and Focus / Tracking / Tilt actuators in an optical disk drive. I.
