Abstract

Alimentation d'un dispositif électronique La présente description concerne un circuit de gestion d'alimentation (400) d'un module électronique comprenant : - une première machine d'état (404) configurée pour recevoir une première commande de désactivation (MOD1_EN) dudit module, et pour vérifier que ladite première commande (MOD1_EN) reste la même pendant une première durée minimale ; et - une deuxième machine d'état (407) configurée pour couper l'alimentation d'au moins une première partie (450) dudit module quand ladite deuxième machine d'état (407) reçoit une deuxième commande (DIS_REQ) de la part de la première machine d'état (404) indiquant que ladite première commande (MOD1_EN) est restée la même pendant une première durée minimale, ladite au moins une première partie (450) dudit module étant alimentée par une première tension d'alimentation (VBAT_FCT1) d'une batterie.
