TDA8596 is programmed to send thermal warning information to the DIAG pin, the DIAG
pin will be pulled LOW. The default thermal pre-warning detection level (IB3[D4] = 0) is
145 C typical. In case IB3[D4] = 1, the detection level is modified to 122 C typical.
In legacy mode the thermal pre-warning level is fixed at 145 C typical.
If the junction temperature increases further, the temperature controlled gain reduction will
be activated for all four channels to reduce the output power (see
