Abstract
UN ACTUADOR (3), POR EJEMPLO FORMANDO PARTE DE UN SISTEMA DE CONTROL DE MOTOR DE VEHICULO, ESTA CONECTADO EN SERIE CON UN FUSIBLE (9) Y EL CAMINO FUENTE-DRENADOR DE UN MOSFET (5) DE POTENCIA ENTRE UN TERMINAL (4) DE SUMINISTRO Y UN TERMINAL (2) DE MASA. UN DECODIFICADOR (6) ESTA CONECTADO AL PUERTO DEL MOSFET (5) COMO PARA PERMITIR QUE EL ACTUADOR (3) A SER ACTUADO SOLO EN RECEPCION DE UN CODIGO. UN DIODO (12) ZENER, UNA RESISTENCIA (11) Y UN DIODO (10) ESTAN CONECTADOS EN SERIE ENTRE EL PUERTO DEL MOSFET (5) Y EL TERMINAL (4) DE ALIMENTACION COMO PARA ACTIVAR EL MOSFET (5) CUANDO TENSIONES EXCESIVAS SEAN APLICADAS AL TERMINAL (4) DE SUMINISTRO, EVITANDO ASI QUE TENSIONES EXCESIVAS SEAN APLICADAS AL CAMINO FUENTE-DRENADOR DEL MOSFET. EL FUSIBLE (9) EVITA QUE CORRIENTES EXCESIVAS PASEN A TRAVES DEL CAMINO FUENTE-DRENADOR DEL MOSFET (5).
