4-channel BTL driver for CD players

BA6392FP

The BA6392FP is a 4-channel BTL driver for CD player motors and actuators. It has an internal primary filter, and can

be directly connected (without attached components) to the servo PWM output of all drivers other than the spindle driver.

The BA6392FP is pin compatible with the BA6297AFP.

FApplications

CD players, CD-ROM drives

FFeatures

1) HSOP 28-pin package allows for miniaturization of

applications.

2) PWM input is filtered by the internal primary filter,

eliminating the need for attached resistors and ca-

pacitors, thereby helping reduce the number of com-

ponents. Resistor and capacitor time constants can

also be changed with attached components.

3) Internal thermal shutdown circuit.

4) Internal mute circuit.
