Diagnostics facility
The TDA7375AV is equipped with a diagnostic circuitry able to detect the following events:
●
●
●
The information is available across an open collector output (pin 10) through a current
sinking when the event is detected A current sinking at pin 10 is triggered when a certain
distortion level is reached at any of the outputs. This function allows gain compression
possibility whenever the amplifier is over driven.
Thermal shutdown
In this case the output 10 will signal the proximity of the junction temperature to the
shutdown threshold. Typically current sinking at pin 10 will start ~10°C before the shutdown
threshold is reached.
