Abstract

Viene descritto un dispositivo elettronico di protezione contro l'eccessiva scarica della batteria di un autoveicolo costituito da un relè pilotabile da un primo transistor. Un contatto del relè è previsto tra la batteria ed un nodo di alimentazione di una pluralità di carichi controllabili da detto dispositivo. In parallelo al contatto è collegato un secondo transistor pilotabile da un terzo transistor pilotato a sua volta in corrispondenza di un livello in uscita da un comparatore. Questo confronta una tensione generata da un partitore di resistenze proporzionale ad una tensione della batteria con una tensione di riferimento. Livelli di tensione a monte e a valle del secondo transistor sono rilevabili mediante rispettivi partitori che generano segnali di tensione direttamente proporzionali ai suddetti livelli di tensione del secondo transistor e confrontabili da un secondo comparatore. Lo stesso comparatore è previsto per il pilotaggio del secondo transistor.
