If the average junction temperature reaches a level that is adjustable via the I

thermal pre-warning is IB3[D4] = 0 setting the warning level at 145 C. In legacy mode the
thermal pre-warning is set at 145 C.
If the temperature increases further, the temperature controlled gain reduction will be
activated for all four channels to reduce the output power (see
