Functional description
The TDA8592J is an audio power amplier with four independent ampliers congured in
Bridge Tied Load (BTL) with diagnostic capability. The amplier diagnostic functions give
information about output offset, load, or short-circuit. Diagnostic functions are controlled
via the I2C-bus. The TDA8592J is protected against short-circuit, over-temperature, open
ground and open VP connections. If a short-circuit occurs at the input or output of a single
amplier, that channel shuts down, and the other channels continue to operate normally.
The channel that has a short-circuit can be disabled by the microcontroller via the
appropriate enable bit of the I2C-bus to prevent any noise generated by the fault condition
from being heard.
7.1 Start-up
When pin STB is LOW, the total quiescent current is low and the I2C-bus lines are
high-impedance.
When pin STB is HIGH, the I2C-bus is biased and then the TDA8592J performs a
power-on reset. When bit D0 of instruction byte IB1 is set, the amplier is activated, bit D7
of data byte 2 (power-on reset occurred) is reset, and pin DIAG is no longer held LOW.
