Optical disc ICs  
6CH Power Driver for  
CD-ROM, DVD-ROM  
BD7902CFS  
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.  
!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 select of spindle driver and standby mode.  
3) Built-in triangular-wave generator.  
4) Package SSOP-A54 has large power dissipation.  
5) Built in thermal-shut-down circuit.  
Spindle driver 〉  
Efficient drive by current feedback PWM drive.  
Built in current limit, hall bias, short brake, FG output and reverse protection circuit.  
Low ON-Resistor. (RON=0.95)  
Sled motor driver 〉  
Efficient drive by current feedback PWM drive.  
Built in 2channel for stepping motor.  
Actuator driver, Loading driver 〉  
Linear BTL drive system.
