8 Detailed Description

8.1 Overview

TPIC2030 is low noise type motor driver IC suitable for 5V optical disk drives. The 7-channel driver IC controlled

by serial I/F is optimum for driving a spindle motor, a sled motor (stepping motor applicable), a load motor, and

Focus / Tracking / Tilt actuators. The integrated current sense resistance for spindle motor current measurement

reduces drive system cost. The spindle motor driver part uses integrated sensorless logic to attain very low-noise

operation during startup and runtime. By using BEMF feedback, external sensors, such as a Hall device, are not

needed to carry out self-starting by the starting circuit or perform position detection. By using the efficient PWM

drivers, low-power operation can be achieved by controlling the PWM outputs. Dead zone less control is possible

for a Focus / Tracking / Tilt actuator driver. In addition, the spindle part output current limiting circuit, the thermal

shut down circuit, and the sled end-detection circuit offer protection for all actuators and motors.
