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.
