TDA2003 power amplifier ICs features short circuit and overheat protection and are suitable for use in car audio
systems. It also delivers 3.5A of output current and additionally
features a thermal shutdown system, according to the datasheet.
It is said that it has protection against DC and AC short circuit between all pins and ground. The picture shows the DC test circuit of TDA2003, which has 18V of maximum operating DC voltage. In the TDA2003 datasheet, you will find sections describe AC/DC short circuit conditions, polarity inversions, load dump voltage surge, thermal shutdown, practical PCB layout,
Assembly and Application sugestions for the car radio designer
(including table contain component lists and value recommendation).
