Abstract

PROCEDIMIENTO DE RETENCION DE DATOS EN CIRCUITOS DIGITALES DURANTE FALLOS PASAJEROS DE LA FUENTE DE SUMINISTRO DE ENERGIA. EN CONDICIONES ESTATICAS UNOS ELEMENTOS DE DIRECCIONADO Y/O ALMACENAMIENTO DEL TIPO LOGICO C-MOS O EQUIVALENTES PRESENTAN UN CONSUMO DE ENERGIA PEQUEÑO, DEBIDO A QUE LAS CORRIENTES DE FUGA SE ALIMENTAN, DURANTE LAS INTERRUPCIONES DE LA FUENTE DE SUMINISTRO PRINCIPAL, POR MEDIO DE LA CARGA ALMACENADA EN UN CONDENSADOR DE CAPACITANCIA ELEVADA (C1). EL RESTO DE LOS CIRCUITOS, INCLUYENDO LOS ELEMENTOS LOGICOS TTL QUE CONSUMEN ENERGIA, SE ALIMENTAN POR SEPARADO A TRAVES DE UN CIRCUITO QUE PRESENTA UNA CONSTANTE DE TIEMPO REDUCIDA, DE TAL MANERA QUE LA TENSION (V2) DISMINUYE CASI INMEDIATAMENTE CUANDO LA TENSION DE ALIMENTACION DE LA RED DESAPARECE. CUANDO SE RESTABLECE EL SUMINISTRO DE ENERGIA, LA INFORMACION HA SIDO CONSERVADA DEBIDO A LA PRESENCIA DE LA TENSION (V1).
