6. Output to VCC, output to GND detection function (pin(9))
The output short detection terminal of pin(9) has open collector output structure on chip as shown in Fig.6.
In unusual case that output terminal of power amp. is condition of output to VCC or output to GND short, 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(9).
