Abstract

LA PRESENTE INVENCION SE REFIERE A UNA CONFIGURACION DE CIRCUITO DISEÑADA PARA DETECTAR EXCESO DE TEMPERATURA DEBIDO AL FLUJO DE CORRIENTE, CON UN ACOPLAMIENTO TERMICO DE UNA PRIMERA CONFIGURACION DE RESISTENCIA Y UNA SEGUNDA CONFIGURACION DE RESISTENCIA, PRODUCIENDO LA RESISTENCIA DE LA SEGUNDA CONFIGURACION DE RESISTENCIA UNA ACCION DE TERMISTOR. LA CORRIENTE A EVALUAR FLUYE A TRAVES DE, AL MENOS, LA PRIMERA CONFIGURACION DE RESISTENCIA. LA PRIMERA CONFIGURACION DE RESISTENCIA CONSTA DE AL MENOS UNA RESISTENCIA SMD Y LA SEGUNDA CONFIGURACION DE RESISTENCIA DE AL MENOS UNA RESISTENCIA SMD QUE ACTUA COMO TERMISTOR. LA SEGUNDA CONFIGURACION DE RESISTENCIA ESTA ELECTRICAMENTE CONECTADA A, AL MENOS, UNA SUPERFICIE DE CONTACTO DE LA PLACA DE CIRCUITO IMPRESO, QUE ESTA CONECTADA A, AL MENOS, UNA RESISTENCIA SMD DE LA PRIMERA CONFIGURACION DE RESISTENCIA.
