5-channel BTL driver for CD players

BA6796FP

The BA6796FP, an IC designed for CD and MD players, has a 5-channel BTL power driver and a standard operational

amplifier. The spindle and tray driver share a single output buffer, and are specified with a control pin. In addition, the

internal level shift circuit reduces the number of attached components.

FApplications

CD players, CD-ROM drives, MD players and other optical disc devices

FFeatures

1) 5-channel BTL driver in a 28-pin HSOP package, al-

lowing for application miniaturization.

2) The five drivers are turned on and off according to

control pin logic combinations.

3) The tray driver operates even when the servo power

supply drops.

4) Internal thermal shutdown circuit.

5) Gain is adjustable with an attached resistor.

6) Internal standard operational amplifier.
