Abstract

Il dispositivo comprende un circuito di discriminazione (10) che genera un segnale digitale il cui livello è indicativo di guasto ed un circuito identificatore (12) che genera un segnale binario (F1, F2) codificante il tipo di guasto rilevato, cioè corto-circuito del circuito di pilotaggio (1) verso massa o carico (5) aperto. Il circuito identificatore (10) comprende una rete resistiva (14) collegata all'uscita (4) del circuito di pilotaggio in modo da generare una tensione (V1) il cui valore dipende dallo stato di corretto collegamento del carico o di guasto ed un comparatore (15) che confronta tale tensione con un valore di riferimento (VREF) per fornire il segnale digitale, mentre il circuito di identificazione (12) comprende uno specchio di corrente (28) generante in uscita una tensione (V2) avente due livelli logici differenti in caso di corto-circuito e in caso di carico aperto. Un circuito combinatorio (34-37) genera il segnale binario (F1, F2) in uscita.Figura 2.
