Optical disc ICs

4-channel BTL driver for CD players

BA6790FP / BA6791FP

The BA6790FP and BA6791FP are 4-channel BTL drivers for CD player actuators and motors. These ICs have internal
5 V regulators and general purpose operational amplifiers, and are mounted to a 28-pin HSOP package, allowing for
the miniaturization of applications.

Applications

CD players and portable CD

Features

1) 4-channel BTL driver.
2) HSOP 28-pin package allows for miniaturization of

applications.

3) Wide dynamic range. (typically 5.4V when V

= 8V

and RL = 8

)

4) Internal thermal shutdown circuit.
5) Gain is adjustable with a single attached resistor.
6) Internal 5V regulator. (requires attached PNP tran-

sistor)

7) Internal general purpose operational amplifier.
