The TPIC2050 is low-noise-type motor driver IC suitable for 12-V ODD. The 9-channel driver, IC controlled by serial interface, is optimum for driving a spindle motor, sled motor (stepping motor applicable), load motor, focus / tracking / tilt actuators, and stepping motor for the collimator lens.
The spindle motor driver part builds in the sensor-less logic that attains low-noise operation at start-up and while running. Motors or sensors, such as a Hall device, are not required by the starting circuit for self-starting, or for performing position detection by BEMF. As the output stage of all channels works in efficient PWM driving, low-power operation by PWM control is possible. Neutral zone-less control is possible for a focus / tracking / tilt actuator driver. In addition, the spindle part output current limiting circuit, thermal shutdown circuit, sled-end detection circuit, collimator lens end detection circuit, actuator protection, and three beam laser drivers are built in. The newly added built-in thermometer can measure IC temperature.
