... TDA7375V vice itself and for the loudspeaker. This particular kind of protection acts in a way to avoid that the device is turned on (by ST-BY) when a resistive path (less than 16 ohms) is present between the output and GND. As the involved circuitry is nor- mally disabled when a current higher than 5mA is flowing into the ST-BY pin important, in order not to disable it, to have the external current source driving the ST-BY pin limited to 5mA ...

... This could be done by taking into account the different timing of the diagnostic output during each case. Normally the clip detector signalling produces a low level at pin 10 that is shorter than that present under faulty conditions; based on this assumption an interface circuitry to differentiate the information is repre- sented in the schematic of fig. 29.

Interface circuitry to differentiate the information schematic 5.9 PCB-LAYOUT GROUNDING (general rules) The device has 2 distinct ground leads, P-GND (POWER GROUND) and S-GND (SIGNAL GROUND) which are practically disconnected from each other at chip level. Proper operation requires that P-GND and S-GND leads be connected together on the PCB-layout by means of reasonably low-resistance tracks ...
