Abstract

UN CIRCUITO DE PROTECCION DE SOBREVOLTAJE EMPLEA UNA SERIE DE ELEMENTOS CONMUTADORES SEMICONDUCTORES, TENIENDO CADA ELEMENTO UNA TERMINAL DE CONTROL Y DOS TERMINALES DE CONDUCCION PRINCIPALES, EN UNA CONFIGURACION DE POLO TOTEM Y DOS DIVISORES DE POTENCIAL CUYOS ALIMENTADORES DE PUNTO DE TOMA, RESPECTIVAMENTE, LAS TERMINALES DE CONTROL Y LAS UNIONES TERMINALES PRINCIPALES DE LOS ELEMENTOS CONMUTADORES. TANTO LA SERIE DE ELEMENTOS CONMUTADORES COMO LOS DOS DIVISORES DE POTENCIAL ESTAN CONEXIONADOS ENTRE UN NODO DE REFERENCIA (CERO VOLTIOS) Y UN NODO PARA SER PROTEGIDO DE UNA DESCARGA ELECTROSTATICA. LOS ELEMENTOS RESISTIVOS DE LOS DIVISORES DE POTENCIAL ESTAN DE UN MODO MONTADOS QUE, EN AUSENCIA DE UNA DESCARGA ESTATICA, TODOS LOS ELEMENTOS CONMUTADORES SE SEPARAN Y EXPERIMENTAN UN VOLTAJE SUSTANCIALMENTE IGUAL A TRAVES DE LAS PRINCIPALES TERMINALES RESPECTIVAS. DE ESTA FORMA, EL CIRCUITO PUEDE EMPLEARSE CON UTILIDAD EN CIRCUITOS INTEGRADOS QUE ESTAN BASADOS EN PROCESOS DE INTEGRACION DE BAJO VOLTAJE PERO QUE TIENEN TAMBIEN UN RAIL DE SUMINISTRO DE VOLTAJE ALTO (POR EJ. 30V). LOS ELEMENTOS CONMUTADORES PUEDEN SER TRANSISTORES BIPOLARES, Y PREFERIBLEMENTE PARES DARLINGTON.
