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擄 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.
4) Package SSOP-A54 has large power dissipation.
5) Built in thermal-shut-down circuit.
