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.
