TPIC2040 Description
TPIC2040 is a very-low noise type motor driver IC suitable for slim or ultra-slim DVD reader/writer. This IC includes integrated current sense resistance that measures SPM current and reduces drive system cost. The 7-channel driver IC controlled by serial I/F is optimum for driving a spindle motor, a sled motor, a load motor, and Focus / Tracking / Tilt actuators.
