Each PlayStation motherboard contains a 4-channel BTL-driver IC, driving the spindle motor, sled motor, focus coil and tracking coil. The inputs are driven by the [[CD_DSP|DSP]].
All of these are 4-channel BTL drivers, driving the spindle motor, sled motor, focus coil and tracking coil. The inputs are driven by the [[CD_DSP|DSP]].


They naturally run relatively warm (hence the large ground pads for heatsinking), but should never get too hot to touch (->IC or something connected to it is probably defective or shorted). All of these have thermal shutdown as a safety feature.
