AUX Input (pin 16)
The pin 16 is for input terminal of AUX
amplifier.
The total gain is 0 dB by using of AUX amplifier.
Therefore, the
-COM can directly drive the
AUX amplifier.
BEEP sound or voice synthesizer signal can be
input to pin 16 directly.
When AUX function is not used, this pin must be
connected to PRE-GND (pin 13) via a capacitor.
5.
Diagnosis Output (pin 25)
This diagnosis output terminal of pin 25 has open collector output structure on chip as shown in Figure 7.
In case diagnosis circuit that detect unusual case is operated, NPN Tr. (Q1) is turned on.
It is possible to protect all the system of apparatus as well as power IC protection.
In case of being unused this function, use this IC as open-connection on pin 25.
5.1
In Case of Shorting Output to VCC/GND or Over Voltage Power Supplied
NPN Tr. (Q1) is turned on.
Threshold of over voltage protection: VCC = 22 V (typ.)
5.2
In Case of Shorting Output to Output
NPN Tr. (Q1) is turned on and off in response to the input signal voltage.
