Afterwards, when the Amplifier is biased, the PERMANENT diagnostic takes place. The previous Turn On state
is kept until a short appears at the outputs.
Fig A: Turn - On diagnostic: working principle
Fig. B and C show SVR and OUTPUT waveforms at the turn-on (stand-by out) with and without TURN-ON DI-
AGNOSTIC.
Fig B: SVR and Output behaviour
CASE 1: without turn-on diagnostic
FIG. C: SVR and Output pin behaviour
CASE 2: with turn-on diagnostic
