- La série innovante ICs S-5470 associée au premier appareil photovoltaïque au monde à consommation d'énergie nulle avec commutateur à détection Light/Dark

TOKYO, 23 juillet 2012 /PRNewswire/ -- Seiko Instruments (SII) a annoncé le 23 juillet la nouvelle série S-5470 de détecteur photo ICs permettant une commutation des circuits à détection light/dark à consommation d'énergie nulle (classe nW) lorsqu'elle est combinée avec une photodiode, une DEL ou autres appareils photovoltaïques.

En raison de l'effet photovoltaïque, les photodiodes et DEL génèrent un très faible courant électrique lorsqu'elles sont exposées à la lumière. Les ICs traditionnelles exigent des amplificateurs pour détecter la minuterie, et donc consomment une énergie significative pour fonctionner. En revanche, la nouvelle série ICs S-5470 de SII détecte la même minuterie sans que les amplificateurs aient besoin d'utiliser la technologie unique CMOS à basse tension de SII. Cela permet également de créer des commutateurs à détecteur d'ombre basés sur les différences de luminosité entre deux appareils photovoltaïques.

Les applications courantes comprennent l'arrêt automatique de la fonction de détection light/dark, l'éclairage automatique dans l'obscurité et la commutation sans contact quand l'appareil est couvert par la main. Quelques exemples : une souris sans fil qui se met en marche lorsque l'utilisateur la saisit pour s'en servir, des smartphones qui s'activent lorsque leur clapet est ouvert, des horloges qui inactivent les carillons en période d'obscurité, un équipement qui fonctionne lorsque la boîte est ouverte, et ainsi de suite.

Caractéristiques de la série ICs S-5470 à très faible consommation d'énergie : 0,1 nA (type) à une tension d'alimentation de 5,5 V, peut s'utiliser avec différents appareils photovoltaïques dont des photodiodes, des DEL, des piles solaires, etc., plage étendue de tension 0,9 V - 5,5 V et petit format SOT-23-5 (2,9 x 2,8 x 1,3 mm).
