... I 7.5 SOAR protection The output transistors are protected by Safe Operating ARea (SOAR) protection. The TDA8594 has a two-stage SOAR protection: • If the differential output voltage across the load is less than 1 V, and the current through the load is more than 4 A, the amplifier channel will be switched off for 16 ms. ...

... When the STB pin is LOW, the total quiescent current is low, and the I be loaded. When the STB pin is switched HIGH, the TDA8594 is put in operating condition and will perform a Power-On Reset (POR), which results in a LOW level DIAG pin. The TDA8594 will start up when instruction bit IB1[D0] is set. Bit D0 will also reset the ‘power-on reset occurred’ ...
