Abstract

Dispositivo di protezione dalla perdita della massa particolarmente per circuiti integrati MOS, il quale comprende un dispositivo high side driver che presenta un morsetto d'ingresso, un substrato riferito a massa ed un morsetto di uscita per il pilotaggio di carichi esterni al dispositivo high side driver stesso. Il morsetto di uscita è realizzato mediante il morsetto di source di un transistore MOS. Al morsetto di uscita è collegato almeno un morsetto di un carico, il cui altro morsetto è riferito a massa. Il dispositivo di protezione comprende almeno un diodo collegante il substrato al morsetto di uscita. Questo diodo collega il substrato alla massa attraverso il carico nel caso che il riferimento a massa del substrato venga interrotto.
