DESCRIPTION

The TDA7241B is a 20W bridge audio amplifier

IC designed specially for car radio applications.

Thanks to the low external part count and com-

pact

Heptawatt

7-pin

power

package

the

TDA7241B occupies little space on the printed

circuit board.

Reliable operation is guaranteed by a compre-

hensive array of on-chip protection features.

These include protection against AC and DC out-

put short circuits (to ground and across the load),

load dump transients, and junction overtempera-

ture. Additionally, the TDA7241B protects the

loudspeaker when one output is short-circuited to

ground.
