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.

FApplications

CD players and portable CD

FFeatures

1) 4-channel BTL driver.

2) HSOP 28-pin package allows for miniaturization of

applications.

3) Wide dynamic range. (typically 5.4V when VCC = 8V

and RL = 8Ω)

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.
