4-channel BTL driver for CD players
BA6398FP
The BA6398FP is a 4-channel BTL driver for CD player motors and actuators. This IC has an internal 5V regulator, and
is suited to a wide range of applications.
FApplications
CD players and CD-ROM drives
FFeatures
1) 28-pin HSOP package allows for miniaturization of
applications.
2) Low number of external components.
3) Driver gain is adjustable with a single attached resis-
tor.
FAbsolute maximum ratings (Ta = 25_C)
4) Internal 5V regulator. (requires attached PNP tran-
sistor)
5) Internal standard operational amplifier.
6) Internal thermal shutdown circuit.
FRecommended operating conditions (Ta = 25_C)

FOperation notes
(1) The BA6398FP has an internal thermal shutdown
circuit. Output current is muted when the chip tempera-
ture exceeds 175_C (typically).
(2) If the mute pin (pin 7) voltage is opened or lowered
below 0.5V, the output current will be muted. Pin 7 should
be pulled up above 2.0V during normal use.
(3) The bias pin (pin 23) is muted when lowered below
1.4V (typically). Make sure it stays above 1.6V during
normal use.
(4) The driver circuit shuts down when the supply volt-
age drops below 4.5V (typically), and starts up again
when the voltage rises above 4.7V (typically).
(5) Muting occurs during thermal shutdown, mute-on
operations or a drop in the bias pin voltage or supply volt-
age. In each case, only the drivers are muted. During
muting, the output pins remain at the internal bias volt-
age, roughly (VCC–VF) / 2.

(6) The internal input resistor has a positive tempera-
ture coefficient of roughly 2000ppm / degree, and so
when changing the gain using an attached resistor, gain
will also change at a rate of roughly 2000ppm / degree.
There is virtually no gain variation due to temperature
when using the internal input resistor.
(7) Be sure to connect the IC to a 0.1µF bypass capaci-
tor to the power supply, at the base of the IC.
(8) The radiating fin is connected to the package’s in-
ternal GND, but should also be connected to an external
ground.
(9) The capacitor between regulator output (pin 6) and
GND also serves to prevent oscillation of the IC, so select
one with good temperature characteristics.
