4-channel BTL driver for CD players

and CD-ROMs

BA5970FP

The BA5970FP is a 4-channel BTL driver developed to drive CD player motors and actuators. The driver input stage

contains an operational amplifier, supports a variety of input formats, and allows simple configuration of a filter.

FApplications

CD players, CD-ROM

FFeatures

1) 4-channel BTL driver.

2) Wide dynamic range (4V when PREVCC = 8V,

POWVCC = 5V, and RL = 8Ω).

3) Internal thermal shutdown circuit.

4) Driver gain is adjustable with externally connected

resistor.

5) Independent power supplies PREVCC, POWVCC (for

channels 1 and 2), and POWVCC (for channels 3 and

4), and low voltage operation for a highly efficient

drive.

6) Independent mute pins for channels 1 and 2 and

channels 3 and 4.

7) Perfect for compact applications with the use of the

HSOP28-pin power package.
