Description

BD7902CFS is a 6-channel driver IC that integrates all drivers necessary for CD-ROM, and DVD-ROM systems into a
single chip. The built-in 2-channel sled motor driver is used for the stepping motor. Low heat operation can be achieved  by applying the PWM driving system for sled and spindle motor drivers.
