5ch Power Driver for
CD-ROM, DVD-ROM
BD7904FS
BD7904FS is a 5-channel driver IC that integrates all drivers and 3.3V regulator necessary for CD-ROM, and DVD-ROM
systems into a single chip. Low head 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, 1channel PWM driver and 3phase motor driver.
- ALL of the motor and actuator for CD-ROM, DVD-ROM etc.
2) ON/OFF for each driver, brake mode switching of spindle, and stand-by mode switching can be controlled by the two
control terminals.
3) Built-in triangular-wave generator.
4) SSOP-A54 for strong head radiation.
5) Built in thermal-shut-down circuit.
6) FG 3phase synthetic output.
