... 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 TDA8595 is put in operating condition and will perform a power-on reset, which results in a LOW-level DIAG pin. The TDA8595 will start up when instruction bit IB1[D0] is set. Bit D0 will also reset the ‘power-on reset occurred’ ...
