6. Output to VCC, output to gnd short 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).
(Application)
7. Rapid ripple discharging circuit at the time of VCC off
This circuit is effective in such a mode where the VCC and the stand-by terminals become high or low
simultaneously; for instance, for a pop noise produced when the power is turned on or off repeatedly by
operating the ignition key.
When VCC is off, this detection circuit detect VCC≒8V internally on IC.
(1) The power stage bias circuit is cut.
(2) pin(8): Ripple capacitor is rapidly discharged by turning Q3 on and then Q1 and Q2 on.
