6-channel BTL driver for CD player

ROHM Semiconductor 

Optical disc ICs

(6) If the voltage of the thermal shutdown or bias pin

drops, the mute is activated; however, in both these situ-

ations, only the drivers and regulator are muted. Also, the

output pin voltage becomes the internal bias voltage

(approx. (VCC*VF) / 2 [for channels 1, 2, 4, and 5], VCC / 2

[for channels 3 and 6]).

(7) Connect a bypass capacitor (approx. 0.1µF) be-

tween the bases of the power supply pins of this IC.

(8) The regulator characteristics are explained below.

The limiting current and ground current can be set by

changing the external current limiting resistor and exter-

nal PNP transistor hfe.

∗ Do not use loads that will change the regulator load

characteristics and regulator current limiting character-

istics. Doing so may cause start-up malfunctions.

(9) The application example will assure excellent re-

sults, but nevertheless, be sure to carefully check all

characteristics during use. During use with constants in

the external circuitry modified, be sure to leave a suffi-

cient margin in order to take into consideration fluctua-

tions in the static and transient characteristics of the ex-

ternal components and this IC.

Also, be aware that ROHM has not sufficiently performed

all confirmations regarding patent rights.
