I2C-bus controlled 4
45 W best efficiency amplifier
information is seen at pin DIAG as a logical OR. In case of a failure, pin DIAG remains
LOW and the microcontroller can read the failure information via the I2C-bus; pin DIAG
can be used as a microcontroller interrupt to minimize I2C-bus traffic. When the failure is
removed, pin DIAG is released.
To enable full control over the clipping information, pin STB can be programmed as a
second-clip detection pin. The clip detection level can be selected for all channels at once.
The clip information can be selected to be available separately at pin DIAG or at pin STB
for each channel. It is possible, for example, to distinguish between clipping of the front
and the rear channels.
The diagnostic information available at either of the two diagnostic pins DIAG and STB is
shown in Table 4.
7.6.1 Start-up diagnostics with DC load detection
If the start-up diagnostics are enabled, the load condition of all four channels is
determined. At the end of the start-up diagnostics cycle, not only the load condition is
known (shorted load, normal load or open load), but also if a separate amplifier is
connected or if the outputs are shorted to battery or ground. If a separate amplifier
(booster) is detected, the amplifier can start-up in line driver mode (low gain setting).
