BD7905BFS Optical disc ICs 6CH Power Driver for CD-ROM, DVD-ROM BD7905BFS BD7905BFS is a 6-channel driver IC that integrates all drivers necessary for optical disc driver. Low vibration, low noise, and low heat operation have been realized by adopting 180° PWM driving system for spindle motor driver. The built-in 2-channel sled motor driver is used for the stepping motor. !Applications CD-ROM, DVD-ROM !Features 1) 3channel BTL driver, 2channel PWM driver and 3phase motor driver. - ALL of the motor and actuator for CD-ROM, DVD-ROM etc. 2) These mode is able to be selected by the two control terminals. - ON/OFF of loading, and other 5channels, brake mode and gain select of spindle driver and standby mode. 3) Built-in triangular-wave generator.
