- La innovadora S-5470 Series ICs combinada con un dispositivo fotovoltaico consigue el primer interruptor de detección luz/oscuro de consumo eléctrico cero del mundo -

TOKIO, 23 de julio de 2012 /PRNewswire/ -- Seiko Instruments (SII) anunció el 23 de julio la nueva serie S-5470 de detector de foto ICs que permite el diseño de circuitos de interruptor de detección luz/oscuro con un consumo eléctrico cero (clase nW) cuando se combina con un fotodiodo, LED, u otro dispositivo fotovoltaico.

Debido al efecto fotovoltaico, los fotodiodos y LEDs generan pequeñas corrientes eléctricas cuando se exponen a la luz. Los ICs convencionales requieren amplificadores para sentir la diminuta corriente, y consumen gran cantidad de corriente para operar. En contraste, el nuevo S-5470 series ICs de SII detecta la misma corriente diminuta sin la necesidad de amplificadores empleando una tecnología CMOS de baja potencia única de SII. Esta aproximación ha conseguido el diseño de circuitos de consumo eléctrico cero (clase nW). También permite el diseño de interruptores de detección de sombra basados en diferencias de iluminación entre dos dispositivos fotovoltaicos.

Las aplicaciones típicas incluyen la funcionalidad de auto-apagado detectando condiciones de luz/oscuro, iluminación automática durante la oscuridad, e interrupción sin contacto cuando el dispositivo está cubierto por una mano. Algunos ejemplos podrían ser un ratón inalámbrico que se enciende solo cuando el usuario lo toca para usarlo; smartphones que se activan cuando se abre la funda; relojes que inactivan las campanadas durante los periodos de oscuridad; equipamiento que opera cuando su caja se abre, y mucho más.

El S-5470 series ICs está caracterizado por consumo eléctrico super-bajo: 0.1 nA (tip.) con un voltaje de suministro de 5.5V; puede ser empleado con una serie de diferentes dispositivos fotovoltaicos incluyendo fotodiodos, LEDs, baterías solares, etc.; amplia gama de voltaje operativo: 0.9V-5.5V; y paquete pequeño SOT-23-5 (2,9 x 2,8 x 1,3 mm.)
