4-channel BTL driver for CD players
and CD-ROMs
BA5916FP-Y
The BA5916FP-Y contains a 4-channel BTL driver for CD player and CD-ROM motors and actuators and a multi-pur-
pose operational amplifier. Perfect for compact applications with the use of the HSOP 25-pin package.
FApplications
CD players, CD-ROM
FFeatures
1) 4-channel BTL driver.
5) Gain is adjustable with externally connected resistor.
6) Internal multi-purpose operational amplifier.
2) Perfect for compact applications with the use of the
HSOP 25-pin power package.
7) Standby pin allows IC to enter power saving mode.
3) Wide dynamic range (3.6V (Typ.) when VCC = 5V and
RL = 8Ω).
4) Internal thermal shutdown circuit.

FOperation notes
(1) The BA5916FP-Y contains a thermal shutdown cir-
cuit.
(4) If the voltage of the thermal shutdown or bias pin
drops, themuteisactivated;however, inthesesituations,
only the drivers are muted.
When the chip temperature reaches 175_C (Typ.), the
output current is muted. If the chip temperature then
drops below 150_C (Typ.), then the mute is released.
(2) By having the standby pin (pin 8) voltage open or
lowered to 0.5V or below, the drivers turn off and the IC
enters the power saving mode.
Also, the output pin voltage becomes the internal bias
voltage (approx. VCC*VF/2).
(5) Connect a bypass capacitor (approx. 0.1µF) be-
tween the bases of the power supply pins of this IC.
(6) Even though the radiation fins are connected to
ground within the package, be sure to also connect them
to a ground externally as well.
For normal operation, have the standby pin (pin 8) volt-
age pulled up to 2.0V or greater.
(3) Ifthevoltageofthebiaspin(pin2)dropsbelow1.0V
(Typ.), outputs are muted. For normal conditions, have
the voltage above 1.4V.
