2-channel BTL driver for CD players

BA5912AFP-Y

The BA5912AFP-Y is a 2-channel BTL driver developed to drive CD player motors and actuators. Perfect for compact
applications with the use of the HSOP 25-pin package.

FApplications
CD players, CD-ROM

FFeatures

1) 2-channel BTL driver.

2) Perfect for compact applications with the use of the
HSOP 25-pin power package.

3) Wide dynamic range.

4) External mute pin enables the muting of the output
current (independent muting for channels 1 and 2).
Muting both channels causes the IC to enter the
standby mode.

5) Two internal multi-purpose operational amplifiers.

6) Power supply is divided into three systems (Pre V
Pow V

CC for channel 1, and Pow VCC for channel 2)

7) Internal standard two operational amplifier.

8) Internal thermal shutdown circuit.
