BA5961FV
BA5961FV is 1ch BTL driver IC for tilt coil driving used for DVD-ROM / DVD-RAM / CD-ROM / CD-RW.
2 general-purpose operational amplifiers are integrated into the small package, this IC has achieved a reduction of its size,
and external components.
This IC can be used not only for tilt coil, but also for wide variety of applications.
!Applications
DVD-ROM, DVD-RAM, CD-ROM, CD-RW
!Features
1) 1ch BTL driver.
2) SSOP-B20W power package enables the smallest configuration.
3) Separating VCC into Pre and Power can be make better power efficiency.
4) Built in level shift circuit.
5) Built in thermal-shut-down circuit.
6) Built in three operational amplifiers .(Two general purpose operational amplifiers and one pre operational amplifier.)
