Abstract[English]
The present application discloses a power supply protection circuit (300), comprising a first polarity protection circuit (PCC1), for receiving a first power source voltage (Vss1) to supply power to a target electronic component (EL) and a first monitoring module (MB1), configured to monitor an output voltage of the first polarity protection circuit (PCC1), and output an alert signal indicating a fault in the first polarity protection circuit (PCC1) when a voltage difference between the output voltage of the first polarity protection circuit and the first power source voltage (Vss1) is less than a polarity monitoring threshold.[French]
La présente demande concerne un circuit de protection d'alimentation électrique (300), comprenant un premier circuit de protection de polarité (PCC1), destiné à recevoir une première tension de source d'alimentation (Vss1) pour alimenter un composant électronique cible (EL) et un premier module de surveillance (MB1), configuré pour surveiller une tension de sortie du premier circuit de protection de polarité (PCC1), et émettre un signal d'alerte indiquant un défaut dans le premier circuit de protection de polarité (PCC1) lorsqu'une différence de tension entre la tension de sortie du premier circuit de protection de polarité et la première tension de source d'alimentation (Vss1) est inférieure à un seuil de surveillance de polarité.
