Title (EN) ELECTRONIC DEVICE FOR COMMUTATION OF ELECTRIC LOAD CONTROLLED BY A MICROCONTROLLER
(FR) DISPOSITIF ELECTRONIQUE DE COMMUTATION DE CHARGE ELECTRIQUE COMMANDE PAR MICROCONTROLEUR
Abstract:
(EN) The invention relates to an electronic device (10) for commuting an electric load, comprising an electronic commutator (16) controlled by a microcontroller (12), positively supplied at a voltage (Vcc), with an outlet which may adopt at least three states and operating in a 'nominal' mode which may be switched intentionally or by default to a 'failsafe' mode in case of malfunction of said electronic commutation device (10), characterised in that said electronic commutation device (10) additionally comprises: a positive commuted supply (Vbat) greater than (Vcc) and connected to the microcontroller (12) of the electronic commutation device (10) by a resistive polarisation device (14) to carry out the function of safety barrier, and an interface device (18) for recognising the presence or absence of commuted supply (Vbat). The invention further relates to a method for operating such a device.
(FR) L'invention concerne un dispositif électronique (10) de commutation de charge électrique comprenant un commutateur électronique (16) commandé par microcontrôleur (12) alimenté positivement sous une tension (Vcc), comprenant un port de sortie à au moins trois états et fonctionnant dans un mode 'nominal', ce dernier étant apte à passer dans un mode 'dégradé' intentionnellement ou par défaut en cas de défaillance dudit dispositif électronique de commutation (10), caractérisé en ce que ledit dispositif électronique de commutation (10) comprend, en outre : une alimentation positive commutée (Vbat) supérieure à (Vcc) et reliée par un dispositif de polarisation résistif (14) au microcontrôleur (12) du dispositif électronique de commutation (10) pour faire office de barrière de sécurité ; et un dispositif d'interface (18) permettant de reconnaître la présence ou l'absence de l'alimentation (Vbat) commutée. L'invention concerne également un procédé de fonctionnement d'un tel dispositif.
