5.8 HANDLING OF THE DIAGNOSTICS INFORMATION
As various kinds of information is available at the same pin (clipping detection, output fault, thermal prox-
imity), this signal must be handled properly in order to discriminate each event.
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.
