4-channel BTL driver for CD players and CD-ROM drives

Optical disc ICs

FOperation notes

(1) The BA5913FP-Y has a thermal shutdown circuit.

The output current is muted when the chip temperature

rises above 175_C (typically). When the chip tempera-

ture falls to 150_C (typically), the driver circuit starts up

again.

(2) Can be set that if the voltage of the standby pin

(pin 8) is open or falls below 0.5V, the driver turns off and

enters the power save mode. During normal operation,

have pin 8 pulled up to over 2.0V.

(3) Muting occurs when the bias pin (pin 2) drops below

1.0V (typically). Make sure it stays above 1.4V during

normal use.

(4) Muting occurs during thermal shutdown or a drop in

the bias pin voltage. In each case, only drivers are muted.

During muting, the output pins remain at the internal bias

voltage, roughly (VCC–VF) / 2.

(5) Connect the IC to a 0.1µF bypass capacitor be-

tween power supplies, at the base of the IC.

(6) Connect the heat radiation fin to an external

ground.
