6. Output to V
7. Rapid ripple discharging circuit at the time of V
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 V
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).
This circuit is effective in such a mode where the V
