SLIS167 – AUGUST 2015
5 Description (continued)
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.
