Short-circuit protection

The TDA2050 has an original circuit which limits the current of the output transistors. The

maximum output current is a function of the collector emitter voltage, hence the output

transistors work within their safe operating area. This function can therefore be considered

as being peak power limiting rather than simple current limiting. It reduces the possibility

that the device gets damaged during an accidental short-circuit from AC output to ground.
