TDA7241B 20W BRIDGE AMPLIFIER FOR CAR RADIO VERY LOW STAND-BY CURRENT GAIN = 32dB OUTPUT PROTECTED AGAINST SHORT CIRCUITS TO GROUND AND ACROSS LOAD COMPACT HEPTAWATT PACKAGE DUMP TRANSIENT THERMAL SHUTDOWN LOUDSPEAKER PROTECTION HIGH CURRENT CAPABILITY LOW DISTORTION / LOW NOISE 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- Figure 1: Test and Appliication Circuit Heptawatt ORDERING NUMBER: TDA7241BH 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.
