Preliminary data sheet
7.1 Start-up
Table 3:
To keep the output pins on the front side, shift bending is applied.
The TDA8592J; TDA8592Q is an audio power amplifier with four independent amplifiers
configured in Bridge Tied Load (BTL) with diagnostic capability. The amplifier diagnostic
functions give information about output offset, load, or short-circuit. Diagnostic functions
are controlled via the I
short-circuit, over-temperature, open ground and open V
occurs at the input or output of a single amplifier, 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 I
noise generated by the fault condition from being heard.
When pin STB is LOW, the total quiescent current is low, and the I
high-impedance.
When pin STB is HIGH, the I
performs a power-on reset. When bit D0 of instruction byte IB1 is set, the amplifier is
activated, bit D7 of data byte 2 (power-on reset occurred) is reset, and pin DIAG is no
longer held LOW.
