LV47002P 4. self-diagnostics function (pin 25) by detecting the unusual state of the ic, the signal is output to the pin 25. also, by controlling the standby switch after the signal of the pin 25 is detected by the microcomputer, the burnout of the speaker can be prevented. (1) shorting to v cc /shorting to ground : the pin 25 becomes the low level. (2) load shorting : the pin 25 is alternated between the low level and the high level according to the output signal. (3) output offset detection : wh en the output offset voltage exceed s the detection threshold voltage, the pin 25 becomes the low level. * note: the output offset abnormality is thought of as the leakage current of the input capacitor. in addition, the pin 25 has become the npn open collector output (active low). the pin 25 must be left open when this function is not used. + - + - + + 16 25 5v speaker pin output voltage +1.8v (typical) -1.8v (typical) time time 0v offset diag out + out - rt in ac gnd output voltage 25 pin voltage fig3 self-diagnosis function diagram no.a1542-5/9
