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 VCC/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
: when the output offset voltage exceeds 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.
